KCET2019PhysicsKinetic Theory of Gases
One mole of ( 4 ) gas is heated at constant pressure starting at ( 27 ^ C . ) How much energy must be added to the gas as heat to double its volume?
Options
- A( 750 R )
- BZero
- C( 1050 R )
- D( 450 R )
Correct answer
C. ( 1050 R )
Step-by-step solution
(C) At constant pressure it volume is doubled, temperate gets doubled, ( T₁=300 k , T₂=600 k ) hence ( T=600-300=300 k ) ( Q=n c_ p T=1 7 2 R 300=1050 R )
