Kinetic Molecular Theory

-
5-At a given temperature, the average kinetic energy of all gases is the same
-
Surface Tension
-
It is a property of liquids, displayed as if it is a stretched elastic membrane, we can see this phenomenon in water droplets and soap bubbles, surface tension is why insects such as water striders can stand on top of water
It depends on the attractive forces between liquid particles themselves and the attraction between liquid particles and solid, gas and liquid it comes in contact with
Water particles have weak attractions between each other, but within a water droplet the water molecules are equally attracted by surroundings in all directions. So when the water is displaced slightly outwards it is attracted back by surrounding molecules
We can think of surface tensions energy as the work and energy needed to remove surface layer in one unit area

The atmospheric pressure inside body=atmospheric pressure outside body (that's why we aren't crushed by the atmosphere)
Elastic collisions//are ideal gases collisions it is when the kinetic energy is not lost nor is it gained (called perfectly elastic)
Thermal energy = 0 is when all possible movements are paused and is the lowest possible temperature in the universe

Pascals principel
When applying a pressure to a confined liquid , the pressure is distributed to all parts of the container and in all directions
