Heat and Thermodynamics question

2019 · 10 Apr · Shift 2 · Q58

JEE MainPhysicsHeat and ThermodynamicsMCQ+4 / −1
One mole of ideal gas passes through a process where pressure and volume obey the relation P=P0[1−12(V0V)2]P = {P_0}\left[ {1 - {1 \over 2}{{\left( {{{{V_0}} \over V}} \right)}^2}} \right]P=P0​[1−21​(VV0​​)2]. Here P0 and V0 are constants. Calculate the change in the temperature of the gas if its volume changes form V0 to 2V0
