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 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 ?

Answer the questions on the basis of given information A molecule of gas collides with the wall of a container elastically. Only ... A ... of the velocity of the molecule changes after collision. Here, A refers to

A particle A is projected with an initial velocity of 60 m/s at an angle 30^(@) to the horizontal. At the same time a second particle B is projected in opposite direction with initial speed of 50 m/s from a A point at a distance of 100 m from A. If the particles collide in air, find (a) the angle of projection of particle B (b) timewhen the collisions takes place and (c) the distance of P from A. where collision occurs. (g=10 m//s^(2))
