first law of thermo

Question 1

specific heat capacity

Answer 1

thermal energy per unit mass to raise the temperature of a substance by one degree kelvin

Question 2

First Law of Thermodynamics

Answer 2

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

Question 3

internal energy

Answer 3

sum of kinetic energy due to random motion of a distribution of particles and potential energies due to intermolecular forces between the particles
