An ideal gas in a cylinder is compressed adiabatically to one-third of its original volume. A work of 
is done on the gas by the process. The change in internal energy of the gas and the heat flowed into the gas, respectively are
A
and zero B
and zero C
and heat flows out of the gas D
and heat flows into the gas
Text Solution
Verified by ExpertsThe correct answer is:
A
From first law of thermodynamics
For adiabatic process, 
Since work is done on the gas.
