A container made up of Aluminium is at `30^@`. It is filled with hydrogen gas to `80^@C`. Answer the following basing on above information.
The temperatures of both (vessel & ion) reaches to `45^@C`. Does heat transfer take place ?

A container made up of Aluminium is at 30^@ . It is filled with hydrogen gas to 80^@C . Answer the following basing on above information. What is the average kinetic energy of free electrons of the metal if the average kinetic energy of H_2 ion is 20 units ?

A container made up of Aluminium is at 30^@ . It is filled with hydrogen gas to 80^@C . Answer the following basing on above information. What is the change when an ion of hydrogen collides with some velocity ? Compare with its initial velocity after collision takes place.

A sphere of 0.047 kg aluminium is placed for sufficient time in a vessel containing boiling water , so that the sphere is at 100 ^(@) C . It is then immediately transferred to 0.14 kg copper calorimeter containing 0.25 kg water at 20^(@) C . The temperature of water rises and attains a steady state at 23 ^(@) C . Calculate the specific heat capacity of aluminium.
