Homework Answers
In isothermal process temperature remain constant so change in internal energy is equal to zero.
So change in internal energy is not equal to zero is incorrect.
PV= nRT
Pressure change correct
No work done Incorrect.
heat added to. the gas Incorrect
temperature remain constant correct.
Thanks! please rate it up.

A monatomic ideal gas undergoes isothermal expansion from 0.08 m3 to 0.22 m3 at a constant temperature (initial pressure is 310 kPa). What are its (a) internal energy change (ΔEΔE), (b) net heat transfer (Q), and (c) net work done (W)? Use negative quantity for heat transfer out of the system or work done on the system.

400 moles of an ideal monatomic gas are kept in a cylinder fitted with a light frictionless piston. The gas is maintained at the atmospheric pressure. Heat is added to the gas. The gas consequently expands slowly from an initial volume of 10 m3 to 15 m3. (a) Draw a P-V diagram for this process. (b) Is this thermodynamic process an isothermal expansion, an isobaric expansion or an adiabatic expansion? (c) Calculate the work done by the gas. (d) Calculate...
