When the molecules are cold they lose energy and come closer together(contracting) and when they are hot they gain energy and move further apart(expanding). An excellent example is water. When molecules are hot they speed up and move around a lot faster. When they are cool they move much slower.

What happens to salt when it is put into cold water and stirred?
When salt is added to cold water and stirred, the salt crystals dissolve in the water. This process is known as dissolution, where the salt molecules break apart from the crystal structure and mix evenly with the water molecules. It may take longer for salt to dissolve in cold water compared to hot water due to the lower kinetic energy of the molecules.
What happens when you drop a sugar cube in cold water using diffusion?
When a sugar cube is dropped in cold water, the sugar molecules start to dissolve due to diffusion. Diffusion is the process by which molecules move from an area of higher concentration to an area of lower concentration to achieve equilibrium. As the sugar molecules spread out in the water, the sugar cube eventually dissolves completely.
Why does cold water have more molecules than hot water?
You may want to frame this question in this manner, "Why does cubic unit of cold water have more molecules than same cubic unit of hot water" This is so because heat causes movement in molecules and malkes them move apart. Hence the hotter the water, the further apart the molecules. Therefore, cold water has more molecules than hot water of same unit.
How are the water molecules positioned in the hot cup?
In a hot cup of water, the water molecules have higher kinetic energy and are moving faster than in a cold cup. This results in the water molecules being more spread out and having increased motion, leading to a less structured arrangement compared to cold water.
What way do cold air molecules move?
In cold air, molecules move slower then they would move in warm air. One part of the KPM (kinetic particle model) states that temperature directly effects the movement of the particles, therefore causing the molecules of the warm air to move faster (because of more frequent collisions between the molecules).
What happens to the water molecules when the air above gets cold?
the water molecules get cold and expand and turn into ice
What happens to the molecules of air when they are heated?
they get exited and move faster than cold molecules
When you beathe on cold window what happens?
the water molecules in your breath condenses as moisture on the glass.
Which of these events happens first in Earth's polar regions A Denser water sinks B Water travels as a deep current C Water molecules move closer together D Cold air chills water molecules?
In polar regions of Earth, FIRST, cold air chills the water molecules.
What happens to the sugar when it dissolves into cold water?
the sugar particles gets adjusted between the spaces of water molecules.
What motion do molecules move when in cold water?
does molecules move in cold water
Does evaporation happen quicker in cold temperature?
No, evaporation happens quicker at higher temperatures because the heat provides energy for water molecules to escape into the air. Cold temperatures slow down the movement of water molecules, reducing evaporation rates.
Are molecules in hot water different then molecules in cold water?
If you have the same volume of both then there are in cold water more molecules.
What happens to a balloon when it is in cold temperature?
In cold temperatures, the air inside a balloon cools and contracts, causing the balloon to deflate or shrink. This happens because the molecules in the air lose energy and move closer together, reducing the pressure inside the balloon.
How do you think molecules move in hot and in cold air?
In hot areas the molecules move quickly and in cold areas the molecules move slower.
Can you give me the characteristics of freezing?
The characteristics of freezing is when water (or any other liquid) turns into a solid. This happens when the liquid gets cold and the molecules get closer together. When the molecules get closer together, they form a solid (ice).
What happens to water when it's very cold?
When water molecules get cold, they slow down any movement. If they get too cold they stop moving completely, causing freezing. However, some liquids can get to below freezing temperatures and still not freeze solid.
