What happens to density of a substance during thermal expansion?
Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.

Higher the temperature the lower the density

What happens to density during evaporation of salt water?
The density increase.
What happens to the original substance during a chemical reaction?
The original substances are transformed during a chemical reaction a new substance (compound) is obtained.
What happens to a substance during between solid and liquid?
It can melt into a liquid, it can be juiced,
Is an instant rapid and hot expansion of the universe the same thing as an explosion?
No. An explosion is an expansion of matter from a central point of high density to outer points of lower density. This is NOT what happened during the Big Bang, despite numerous popular presentations to that effect. The Big Bang was NOT an expansion of dense matter from a central point into empty space. It was an expansion of space itself.
What happens to a substance during changes between solid and liquid?
It can melt into a liquid, it can be juiced,
What happens to substance during changes between solid and liquid?
It can melt into a liquid, it can be juiced,
What happens to a substance during changing between a solid to a liquid?
When a substance changes from a solid to a liquid and vice versa, its density changes.
What happens to a substance during changes between solid and I gas?
When a substance changes from a solid to a gas, called sublimation, it quickly becomes less dense.
