The possibility of increase in the temperature of a gas without adding heat to it happens in
A
Adiabatic expansion
B
Isothermal expansion
C
Adiabatic compression
D
Isothermal compression
Answer
Adiabatic compression
Explanation
Solution
: In adiabatic process
}{ordU = - dW}$$ In the process of compression, work is done on the gas therefore dW is negative. Hence dU is positive i.e. internal energy of gas increase and therefore temperature of the gas also increase
