Question

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

Answer 1

Answer:

Density of gas decreases as temperature of the system increased.simple example is hot air balloon works on the same principle.

This is because as temperature increases gas expands thus it's volume increases for same mass and density of the gas decreases as a result.

Answer 2

Explanation:

when when we increase the temperature of gas molecules, as such the kinetic energy of molecules increases which means the volume increases
