When a gas is compressed isothermally, the product of its pressure and volume during the process is:
Correct answer: B. constant
- A. not constant
- B. constant
- C. zero
- D. proportional
Explanation
According to Boyle's law, which applies to an ideal gas undergoing an isothermal process, the product of pressure and volume remains constant: P × V = Constant

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.
