For an isochoric process, which of the following statements is NOT true?
Options
- AT = 0
- BV = 0
- CW = 0
- DQ = U
Correct answer
A. T = 0
Step-by-step solution
An isochoric process is a thermodynamic process in which the volume of the system remains constant. Since the volume is constant, the change in volume is zero, so V = 0 . The work done by the gas is given by W = P V . Since V = 0 , the work done is W = 0 . According to the first law of thermodynamics, Q = U + W . Substituting W = 0 , we get Q = U . In an isochoric process, the temperature can change (for example, when heat is added to a gas in a rigid container, its temperature and pressure increase). Therefore, T
