What is the equation of the change in thermal energy?

Answer 1

Heat energy is measured in calories, or it can be in BTU. (1 BTU = 252 calories)

1 calorie is the heat required to raise 1 gram of water by 1 deg celsius

1 BTU is the heat required to raise 1 lb of water by 1 deg Fahrenheit.

If you are using another fluid or substance, you need to know its specific heat capacity, that is its heat capacity compared with water, then you can adapt the calculation of total heat accordingly. If dealing with a fluid which boils, or a solid which melts, you also need to include the latent heat of the phase change in the total, this will be expressed as so many calories/gram or BTU/lb for that substance. Heat is absorbed in melting or boiling, and given out in condensing or freezing.

Answer 2

If you want to calculate quantity of thermal energy, first multiply mass by the specific heat capacity (for liquid water this is 4.19J/g degrees Celsius). Then multiply by the change in temperature times changes of time.

Answer 3

The equation of the change in thermal energy is given by (Q = mc\Delta T), where (Q) is the heat energy transferred, (m) is the mass of the substance, (c) is the specific heat capacity of the substance, and (\Delta T) is the change in temperature.

Answer 4

Thermal Energy is the total energy of the particles in a material, which is measured as: Change in thermal energy= mass X Change in temperature X specific heat.

Answer 5

HE=M times C times P times changes of time

Answer 6

E = kT, where E = energy ,T = temperature and k = Boltzmann Constant

Answer 7

Integral from initial to final of the internal energy or integral from initial to final of the enthalpy.

Answer 8

Q=mC change in temperature
