Because the water molecules which are far inside the liquid experience an outward force, and has no maximum potential energy.

A warmer world is least likely to result in?
A rise in sea level
Why does the air over the equator rise?
Probably because it is warmer and hence lighter.
Why does temperature rise as altitude increases in the stratosphere?
It begins to get warmer from the sun's radiation.
What causes the warm air to rise and the cold air to sink?
The warmer the air is, the more energy the molecules have. The more energy the molecules have, the more they vibrate. When the molecules vibrate, they bounce into each other and push apart from each other, hence the warmer the air is, the less dense it is (number of molecules per unit volume). Colder air has less energy which means more molecules can fit into one space because they are not bouncing off each other.
Does cold air fall?
Cold air sinks because it is more dense than warmer air. The warmer the air is the more energy the molecules have. The more energy the molecules have the more they vibrate. When the molecules vibrate they bounce into each other and push apart from each other, hence the warmer air is; the less dense it is (number of molecules per unit volume). So, colder air has less energy which means more molecules can fit into one space (because they are not bouncing off each other) which essentially makes it heavier.Read more: Why_doesn't_cold_air_rise
Do molecules rise or sink after they are heated?
Rise
Do currents cause warmer and cooler temperatures in the areas where they are located?
No. Currents in the air and oceans are caused by the heat from the sun.
Why is it warmer on the top floor in your house?
Heat has a tendency to rise
As wind attempts to rise over a mountain it becomes?
Warmer
What must molecules do for. Matter to become warmer?
move faster.
What must molecules do matter to become warmer?
move faster.
Why do the air molecules inside a bicycle tire speed up as the temperature gets warmer?
because the heat is transferred to the molecules and gives them more kinetic energy
List 2 examples of heat transfer by convection?
Two examples of heat transfer by convection can be water in a pan being heated and our surrounding atmosphere. First, water in a pan being heated can be picture by imagining the bottom of the pan to be more hotter than that of the top of the pan. If that's true then the molecules in the bottom will rise up and the cooler molecules on the top will go to the bottom and cycles until they are at equal temperature. Second, our atmosphere is also like that of the water in a pan. When we have a hot day the warmer air at the bottom will rise up because the warm air expands and becomes less dense than its surrounding air (so warm air will rise up like a balloon). You can think of it as when we heat up air molecules that are near the ground due to gravity, the warmer the molecules become they tend to be more active or kinetic than the cooler molecules and zip by farther areas which leads them to rise up and cooler molecules in the air go at the bottom and repeats the cycle.

Why do gliders rise when they go over a town?
The air above a town is warmer and the glider can rise on the thermals produced.
How does the movement of molecules in warm objects compare with the movement of molecules in cooler objects?
warmer molecules are more excited and therefore move faster than colder molecules
What happens to the molecules when a solid is melted?
Nothing happens to the molecules. They're just warmer and moving around faster.
A warmer world is least likely to result in?
