it gains energy and particles start to move along in all directions.

It heats up and the water keeps warm for a certain amount of time
The soil and water heats up and makes uneven heating.
The substance in the thermometer stem rises up because it expands when heated. This expansion is due to the particles within the substance moving more rapidly and spreading further apart, causing the substance to take up more volume and rise up the stem of the thermometer.
What do you think happens when some air heats up and other air is cool?
When you heat up particles in a marshmallow, the particles gain energy and move faster. This causes the marshmallow to expand as the air trapped inside heats up and expands, increasing the volume of the marshmallow.

When a substance undergoes thermal expansion, its particles gain energy and move farther apart, causing the substance to increase in volume. This increase in volume is due to the increased average kinetic energy of the particles, leading to the substance taking up more space.
They speed up and moves faster and faster.
