Question

How does the density of gases change with the rise in temperature? ​

Answer 1

Answer:

Since there are now more particles per cubic unit of length, the density increases. Also, when we increase the temperature of the gas molecules, we increase the energy of the molecules. As such, the Kinetic energy of the Molecules increase, which means the volume increases. This mean the intermolecular space increases.

Answer 2

Answer:

In cases of a gas there is large change in volume,with the rise in temperature.thus,the mass of a gas or liquid remaining constant if their volume increases with the rise in temperature then their density will decreases.
