Which of the following is not a thermodynamic coordinate?
1 Gas constant (R)
2 Pressure (P)
3 Volume (V)
4 Temperature (T)
Explanation:
A Pressure (P), Volume (V) and temperature (T) are the thermodynamic coordinates whereas $R$ is a universal gas constant valued at $8.314 \mathrm{~J} \mathrm{~mol}^{-1} \mathrm{~K}^{-1}$

What is the name of ideal-gas process in which no heat is transferred?
1 Isochoric
2 Isothermal
3 Isobaric
4 Adiabatic
Explanation:
D The ideal-gas process in which no heat is transferred between a thermodynamic system and its surroundings is called as adiabatic process.

When you make ice cubes, entropy of water:
1 does not change
2 increases
3 decreases
4 may either increase or decrease depending on the process used
Explanation:
C The entropy function gives us a numerical measure of the irreversibility of a given process i.e. it is a measure of disorder of a system. During formation of ice cubes orderedness increase i.e. disorderness decrease hence, entropy decreases.

What happens to the internal energy of a gas during isothermal expansion ?
1 Internal energy will decrease
2 Internal energy will increase
3 Internal energy will become zero
4 Internal energy will remain same
Explanation:
D In isothermal expansion temperature remains constant. Therefore, internal energy which is a function of temperature will remain constant.
