9 Thermodynamics

Question 1

specific heat capacity

Answer 1

The quantity of heat required to produce a unit change in temperature per unit mass of that substance

Question 2

Specific latent heat of fusion/vaporisation

Answer 2

the amount of heat required
per unit mass
to change a substance from the solid state to the liquid state / liquid state to gas state
without any change in temperature

Question 3

Isothermal
Isovolumetric
Isobaric
Adiabatic

Answer 3

No change in 
Temperature
Volume
Pressure
Heat

Question 4

First law of thermodynamics

Answer 4

The increase in internal energy is the sum of the heat supplied to the system and the work done on the system
U=Q+W

Question 5

WHat is internal emergy

Answer 5

the sum of the random distribution of
microscopic kinetic energy and
microscopic potential energy
of the system

Question 6

Internal energy in ideal gas

Answer 6

In the case of an ideal gas,
intermolecular forces between molecules is negligible
potential energy is taken to be 0
the internal energy is equal to its microscopic kinetic energy
