The plot of pressure on the Y axis and volume on the X axis, at constant temperature is called:
Correct answer: C. Isotherm
- A. None of these
- B. Isochor
- C. Isotherm
- D. Isobar
Explanation
The volume-pressure graph at contant temperature is called an isotherm. It is the graphical representation of the Boyle's Law, which states that the volume of a gas is inversely proportional to the pressure at constant temperature. Mathematically:PV = constant or P1V1 = P2V2 (at constant temperature)

About Thermal Equilibrium and Heat
Thermal equilibrium means that bodies in contact have the same temperature and no net heat flows between them. The topic distinguishes heat from temperature, uses the zeroth law of thermodynamics, and covers heat transfer, specific heat capacity, thermal expansion and the conditions for reaching equilibrium.
