first law of thermodynamics

Question 1

heat capacity

Answer 1

amount of thermal energy required to raise its temperature by 1 K

Question 2

specific heat capacity

Answer 2

amount of thermal energy required to raise the temperature of 1 kg of it by 1 K

Question 3

specific latent heat

Answer 3

thermal energy required to convert 1 kg of a substance to another phase without a change in temperature

Question 4

internal energy

Answer 4

sum of the random distribution of kinetic and potential energies associated with the molecules of a system

Question 5

first law of thermodynamics

Answer 5

the increase in internal energy of a closed system is the sum of the heat supplied to the system and the work done on the system
