An ideal gas undergoes process PV1.25 = constant. Then –
A
Upon increase in pressure temperature decreases
B
Upon increase in pressure heat is absorbed by gas
C
If heat is given to gas its internal energy increases
D
Heat is absorbed by gas if volume increasing
Answer
Heat is absorbed by gas if volume increasing
Explanation
Solution
C = R
{35−11−1.25−11}<0
̃ Temperature decreases if heat is given to gas Also,
PV = nRT =
̃ Temperature decreases with increases in volume and decrease in pressure.
