Question

In isothermal expansion the pressure is determined by :
  1. temperature only
  2. compressibility only
  3. both temperature and compressibility
  4. latent heat

A
temperature only
B
compressibility only
C
both temperature and compressibility
D
latent heat
Solution
Verified by Toppr

In isothermal expansion, the temperature remains constant over the process.

Thus, the pressure is only variable dependent on the volume or the compressibility of the system.
