Answer:
The molecule of gases are separated at far distance from each other in space causing the objects to move freely resulting in the increase in kinetic energy of the molecules.
Explanation:
There are 3 states of matters namely; solid, liquid and gaseous state.
For gases, the molecules are held father apart as such they possesses weak intermolecular force due to the large distance between their molecules. Due to the free nature of this molecules, they are free to move about in space leading to the increase in their kinetic energy. This molecules also tends to collide with one another and the walls of their container causing an increase in their kinetic energy and causing them to move faster in space.
