This is a short answer type question as classified in NCERT Exemplar
Yes during adiabatic compression the temperature of a gas increases while no heat is
In adiabatic compression dQ=0
From the first law of thermodynamics dU= dQ-dW
dU=-dW
in compression work is done on the gas i.e work done is negative
dU=positive
hence internal energy of the gas increases due to which its temperature increases.

From A to B the process is isobaric
= W = 2 × R (600 - 350)
= 500 R
Heat is path dependent so path function but internal energy does not depend on path chosen.
