Heated molecules causes molecules to bounce into each other separating them. As molecules separate, their density, the amount of matter found in a given volume or space, decreases. Cooled molecules are not that loose and start to get packed together if it gets frozen.

When you heat molecules, they gain energy and move faster, increasing their kinetic energy. This can lead to changes in their physical state (e.g. melting, boiling). When you cool molecules, they lose energy and move slower, decreasing their kinetic energy, which can cause them to change state (e.g. freezing).

What happens to space between molecules as they cool?
The space between molecules generally decreases as they cool down. This decrease in temperature causes the molecules to slow down, reducing their kinetic energy and allowing them to move closer together. This process can lead to the molecules eventually forming a solid state.
What happens to some liquids like melted butter when heat is taken away?
When heat is removed from melted butter, it will start to cool down and solidify back into a solid state. This process is known as congealing or solidification, where the liquid fat molecules in the butter begin to rearrange and form a solid structure as they lose heat energy.
What happens to acetone molecules when you add heat to a breaker of liquid acetone?
When heat is added to a beaker of liquid acetone, the acetone molecules gain energy and begin to evaporate into the air as a gas. The increased temperature causes the molecules to move faster and escape the liquid phase.
What happens to heated materials when heat is removed from it?
When heat is removed from a heated material, it begins to cool down. The molecules within the material lose kinetic energy, resulting in a decrease in temperature. As the temperature drops, the material may undergo physical changes, such as solidification or contraction, depending on its properties.
Can evaporation cool or heat a substance?
Evaporation typically cools a substance because as molecules absorb energy to change from liquid to gas, they take away heat from the surrounding environment. However, under certain conditions such as with evaporative cooling systems, evaporation can be used to cool a substance deliberately.
What happens when molecules are removed from heat?
the molecules will decrease in motion
What happens when fast moving molecules touch other molecules?
Heat transfer
What happens to heat during an endothermic reaction?
During an endothermic reaction, heat is absorbed from the surroundings in order to break chemical bonds and allow the reaction to proceed. This absorption of heat causes the surroundings to cool down as energy is taken in by the reacting molecules.
What happens when you change you system from cool to heat and it still blows out cool air?
The furnance is not coming on.
What happens when you heat and cool air?
When you heat air, the air pressure rises and the particles expand.
What happens to the molecules of a substance when it is melted?
the molecules vibrate, faster and faster as the heat increases then they become disordered
What happens when you don't cool down?
Heat stroke and soon after death..... ):
What happens to atoms of A substance when heat is added?
When heat is added to a substance, the molecules and atoms vibrate faster.
What happens if you remove heat from water?
If you remove heat from water, it will cool down and eventually freeze into ice at 0 degrees Celsius. The water molecules will slow down and lose energy as heat is removed, causing them to come together more closely and form a solid structure.
What happens to space between molecules as they cool?
The space between molecules generally decreases as they cool down. This decrease in temperature causes the molecules to slow down, reducing their kinetic energy and allowing them to move closer together. This process can lead to the molecules eventually forming a solid state.
What happens to the molecules of water vapor when the temperature of gas cool to 100c?
The molecules slow down and begin to change back to the liquid state.
What happens to the energy of glucose that is not used to nake atp molecules?
The energy not used to make ATP molecules generates heat.
