The definition says specific heat is the energy required to raise the temperature of a unit mass of a substance by one degree. Specific heat is also known as specific heat capacity.
Crystals, such as quartz, can be tapped for electricity using a piezoelectric (mechanical energy discharge) method. By securing the crystal and subjecting it to direct force with a permanent magnet, a detectable amount of electricity is released. This technology is used in cigarette lighters and gas grill ignition ...
The energy required to evaporate 1 liter of water in 5 minutes depends on several factors, such as the initial temperature of the water, the humidity of the surrounding air, and the pressure.

This webpage is part of the Chemistry LibreTexts library, which provides free and open educational resources for chemistry and related fields.
The strength of a covalent bond is measured by its bond dissociation energy, that is, the amount of energy required to break that particular bond in a mole of molecules. Multiple bonds are stronger …
A barrel of oil equivalent has a LHV of about 35.6 kWh/gal which is very close to the 35.3 kWh/gal LHV figure for a typical gasoline. So 15% x 15% x 35.6 kWh/gal is about 0.8 kWh/gallon of actual electrical …
To calculate the cost of charging a Tesla, you can multiply the kWh required to charge the battery by the cost per kWh of electricity in your area. For example, if the cost of electricity in your area is $0.12 per kWh and your Tesla Model 3 requires 60 kWh to fully charge, it would cost you $7.20 to charge your car.
PV panels have a nearly non-existent carbon footprint, around 40 grams per kWh of electrical energy produced. This only comes from the manufacturing process of making, installing, maintaining as well as disposal of the panels. The energy produced by PV panels is almost clean and the emissions mentioned previously are countered …
This article attempts to estimate the material and energy requirements for the production of REM based on the theoretical chemical reactions and thermodynamics. The results show the material and energy requirement varies greatly depending on the type of mineral ore, production facility, and beneficiation process selected.
Ionization energy is the quantity of energy that an isolated, gaseous atom in the ground electronic state must absorb to discharge an electron, resulting in a cation.
Calculating kWh from amps is quite a challenge. First, we need to convert amps to watts (using voltage), and then we can convert watts to kWh. To make this process easier, we have developed the Amps To kWh Calculator that does all of this automatically.
Food calories are a measure of energy in food. One food calorie is equal to 1,000 calories, or 1 kilocalorie. For example, the energy in a 300 food-calorie ice cream cone is about the same as the amount of electricity required to light a 100-watt incandescent light bulb for 3.5 hours.
In grinding processes, energy consumption is a very important profitability criterion for the applied particular size reduction technology.
A standard infrared heater uses 1500 watts. Infrared heaters use 7 watts per square foot (0.1 m²) compared to 10 watts for standard heaters. To heat an average-sized living room of 330 square feet, 2300 …
The energy consumption of about 32 kWh/t for milling quartz of < 2.5 mm down to < 40 μm is much less than that taken by a ball mill (Schönert 1988 ), i.e. the HPGR mill yields higher energy efficiency than the ball mill.
It assumes the cost of gas is 60 cents a therm, and electricity is 8 cents a kWh: You can customize it to your oven and cooking time with some math. Say you do a little research and find out your oven uses 3.5kW/hour and you need to bake your giant sheet cake for 2 hours straight. 3.5kW/h * 2h * 0.08$/kW = $0.56.
Historically, energy was measured in units of calories (cal). A calorie is the amount of energy required to raise one gram of water by 1 degree C (1 kelvin). However, this quantity depends on the atmospheric pressure and the starting temperature of the water.
Calculate the energy consumption and usage costs of a Quartz Halogen Work Light (500 W). Learn about its cost in dollars of usage and money-saving tips to reduce bills.
It would take roughly 70 pounds of coal to produce the energy required to charge a 66 kWh electric car battery, said Ian Miller, a research associate at the MIT Energy Initiative.
The Energy Cost per SCFM of Your Nitrogen Specification. The higher the percent nitrogen required, the larger the system to obtain a given flow rate. More compressed air will be required and more electricity consumed. Capital cost, long term maintenance cost, and floor space will increase as well.
Ionization energy: period trend. An element's first ionization energy is the energy required to remove the outermost, or least bound, electron from a neutral atom of the element. On …
The specific heat represents the amount of energy required to raise 1 kg of substance by 1 oC (or 1 K), and can be thought of as the ability to absorb heat. The SI units of specific heats are J/kgK (kJ/kg oC) . Water has a large specific heat of 4.19 kJ/kg oC compared to many other fluids and materials . Heat vs. work vs. energy.

Ionization energy (IE) is the energy required to remove an electron from a neutral atom or cation in its gaseous phase. IE is also known as ionization potential.
Electric Immersion Water Heater Running Costs Calculator. Hot water immersion heater elements are usually rated at 3 or 6 Kilowatts (kW). Hot water cylinders/tanks come in many shapes, sizes and capacities, ranging from 40 to over 400+ litres in larger homes. Running a bath will use approximately 60 - 80 litres of water.
How much electricity do air conditioners use? Quite a lot, actually. According to EIA, US s used 235 billion kWh (kilowatt-hours) of electricity just for cooling in 2021. Of course, we are usually most interested in how many kWh does our air conditioner use.
The equation for the amount of thermal energy needed to produce a certain temperature change is as follows: q = cmDeltaT Where: q is the amount of thermal energy c is the heat capacity of water (~~ 4.184 J/g^oC) DeltaT is the change in temperature. So, how much thermal energy you need is dependent on exactly how much you want to …

Calculate Kilowatt-Hours. Calculate the kilowatt-hours (kWh) required to heat the water using the following formula: Pt = (4.2 × L × T ) ÷ 3600. Pt is the power used to heat the water, in kWh. L is the number of liters of water that is being heated and T is the difference in temperature from what you started with, listed in degrees Celsius.
Since heat is a form of energy, its SI unit is the joule (J). Another common unit of energy often used for heat is the calorie (cal), defined as the energy needed to change the temperature of 1.00 g of water by 1.00oC —specifically, between 14.5oC and 15.5oC since there is a slight temperature dependence.
The amount of energy required to create a solar panel varies depending on the type of panel. It takes about 200 kWh of energy to make a single 100-watt solar panel. As technology improves, these numbers change too. Don't worry, though – the idea that solar panels use more energy than they produce is totally untrue.
Explore data on how energy production and use varies across the world.
As noted at the beginning of this chapter, Nicolaus Copernicus first suggested that Earth and all other planets orbit the Sun in circles. He further not...
This is totally and completely false. The PUE of Google and Microsoft is 1.2. This means that 100 watts of server power corresponds to 20 watts of everything else that includes not only cooling but also keeping power uninterrupted by battery UPSes. So cooling is a very minor energy user in a good data center.
