What happens to the molecules in a gas when the gas is heated? Assume that the heating is not sufficient to induce molecular dissociation, and that the gass is in a solid enclosed container. Choose all which apply.
Homework Answers
On adding heat to a substance, kinetic energy of its molecules increases, it's atoms start vibrating more vigorously, spacing between the atoms of a molecule and spacing between the different molecules is increased so change of state may take place, a solid state is converted into liquid state and liquid state into gaseous state. In simple words, internal energy of the molecules is increased on adding heat to them.
