The molecules in matter are in constant motion, and energy added to a material causes its molecules to increase their motion. This results in a larger average area being occupied by each molecule as they interact withe each other.
If the structure of the material is altered by this expansion, a phase change can occur : solid to liquid, or liquid to gas. The molecules in liquids and gases are more easily separated from each other than in solids.

Does heat always flow from cooler objects to warmer?
Heat always flows from warmer objects to cooler objects, unless you have a device (like a heat pump) to prevent this. The natural tendency is for two or more objects at different temperatures to eventually all have the same temperature and this is accomplished by heat flowing from the warmer objects to the cooler objects.

Can thermal energy flow from cooler objects to warmer objects?
energy alwayy flow from high density to low density
What is a true statement about heat?
Heat always flows from warmer objects to cooler objects.
How do solids expand said in detail?
a solid expands by heat because if you decrees the temperature it will make it freeze and if it is warmer it will expand
Why do objects get warmer in the sun?
Because of the heat from the sun ;
How is heat transferred from one object to another (Apex)?
Heat moves from warmer objects to cooler objects.
