For a gas obeying Boyles law if the pressure is doubled the volume becomes________________?
Correct answer: B. one half
- A. double
- B. one half
- C. four times
- D. one fourth
Explanation
Boyle's law at constant temperature states PV = constant, so P1V1 = P2V2. If pressure changes from P to 2P, then V2 = PV1/(2P) = V1/2, so the volume becomes one half; the likely mistake is choosing double because pressure and volume are incorrectly treated as directly proportional.

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.
