A Isothermal processes are necessarily slow because they require heat transfer to remain at the same temperature as being in thermal equilibrium with a reservoir.

The volume of an ideal diatomic gas is doubled isothermally. The internal energy
1 is doubled
2 is halved
3 is increases four times
4 is remains unchanged
Explanation:
D No change in the internal energy of an ideal gas, but for real gas internal energy increases, because work is done against intermolecular forces. In is isothermal change temperature remain constant. Hence internal energy will not change

Which of the following processes is reversible?
1 Transfer of heat by radiation
2 Electrical heating of a Nichrome wire
3 Transfer of heat by conduction
4 Isothermal compression
Explanation:
D For process to be reversible it must be quasistatic. For quasi static process all change take place infinitely slowly. Isothermal process occur very slowly so it is quasi- static and hence it is reversible.

Isothermal process is the graph between
1 Pressure and Temperature
2 Pressure and Volume
3 Volume and Temperature
4 P,V and Temperature
Explanation:
B Isothermal Process is the graph between Pressure and volume
