What happens to the average kinetic energy of a gas when the particles of the gas collide against each other at a constant tempe
rature and volume? The average kinetic energy remains constant. The average kinetic energy drastically increases. The average kinetic energy drastically decreases. The average kinetic energy gets added to the potential energy.
Collisions between gas particles are elastic. An elastic collision means there is no net gain or loss of kinetic energy due to the collision. This means a sample of gas will have a constant average kinetic energy at a constant temperature and volume.
The average kinetic energy drastically increases when the gas particles collide against each other at a constant temperature and volume because the collision will increase the heat content of gas at a particular temperature and gas particles begin to move faster as gain more kinetic energy.
Electromagnetic waves are not like sound waves because they do not need molecules to travel. This means that electromagnetic waves can travel through air, solid objects and even space.
The answer is D because they would have to make quarries just below the surface to mine Mineral ores much quicker (Quarries- a large hole/pit under ground used to get stone and minerals)
