1- Explain the maintaining constant temperature despite of the compression process in Boyle's law.

A monatomic ideal gas is compressed isothermally from a volume of 2.0m^3 to 1.0 m^3. The initial pressure is 20 kPa. a. Find the work done on the gas from initial state to final state. b. Find the change in the internal energy of the gas. c. Find the amount of heat exchanged.
