ne heat gives energy for the particles to move around
The object expands
The object expands
This is becuase it becomes a solid and the particles expand to fit neatly into a solid square.
no it expands with heat, it shrinks when cooled
Most usually, heat expands a solid, making it less dense.
When a solid is heated it expands and if is heated enough it will melt; it may also boil. If you cool it down it will go back to solid form.
solids;there molecules are closer together
Gas is the state of matter that expands when heated and is easy to compress due to the large spaces between its particles.
It expands. Most substances contract on freezing.
TRUE!
Rain is liquid Ice is solid. with water when you cool it (slow the molecules) it expands (which is unique to water) becoming a solid crystal, and since it expands its mass per volume ratio has changed making it less dense then liquid water.
Gas expands to fill up it's container, while if solids are put into the same container, the will not expand. They will stay the same size and shape.
