The average kinetic energy of a gas when the particles of the gas collide against each other at a constant temperature and volume will not changes.
<h3>What is average kinetic energy?</h3>
The product of half the mass of each gas molecule with the square of root mean square speed is the average kinetic energy of the molecules.
And this average kinetic energy is deirectly proportional to the absolute temperature of the system but in the given question temperature and volume of the gas is constant. So that there is no change in average kinetic energy of molecules when they collide.
Hence no change in the average kinetic energy of a gas takes place.

density of the object = 0.53 g/mL
Explanation:
First we need to find the volume of the object which is equal to the rise of the water in the graduated cylinder:
volume = 31.7 - 25.1 = 6.6 mL
Now we calculate the density of the object using the following formula:
density = mass / volume
density = 3.5 g / 6.6 mL
density = 0.53 g/mL
