kinetic energy is needed by the molecules in order to escape from the surface.
All the water molecules in the liquid are moving randomly due to the presence of some energy in it. Some of the molecules have more kinetic energy due to absorption of heat energy from the surrounding environment.
Due to high kinetic energy, these molecules move enough to escape the surface of the liquid. This is called boiling point. This makes the liquid become gas so we can conclude that kinetic energy is needed by the molecules in order to escape from the surface.

Answer:
42 kg.m/s if the two are moving in the same direction
Explanation:
momentum formula: p=mv
22kg.m/s+20kg.m/s= p
42kg.m/s=p
the momentum of both objects=42 kg.m/s
Answer:
A whole lot of zig-zagging: Perhaps that is what happens when the universe's mysterious dark matter particles hit the Earth. ... Dark matter particles can penetrate all other forms of matter, which means that they may even be able to traverse right through our planet without losing any energy whatsoever.
Explanation:
Explanation:
production of living organism from nom living matter is known as spontaneous generation.
