Verified by Experts
The correct answer is:
A

To determine the change in temperature when a gas is adiabatically compressed, we are given the following initial conditions:

Initial volume,
Final volume,
Initial temperature,
Adiabatic index (ratio of specific heats)
In an adiabatic process, the relationship between temperature and volume is given by the equation:
constant
Applying this to the initial and final states:

Solving for the final temperature :

Thus, the change in temperature is:

Therefore, when the gas is adiabatically compressed, the temperature increases by 300 K.
