When a sample of a gas is heated in a sealed, rigid container from 200. k to 400. k, the pressure exerted by the gas is
(1) decreased by a factor of 2.
(2) increased by a factor of 2.
(3) decreased by a factor of 200.
(4) increased by a factor of 200.

conduction is the transfer of thermal energy (heat in transfer) due to collisions between the molecules in the object. collisions between adjacent atoms and molecules transfer kinetic energy from the warmer to the cooler object. the objects must be in physical contact.
