Q. What happens when heat is added to a solid?
When a solid is heated the particles gain energy and start to vibrate faster and faster. At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.
Q. What happens if heat is removed from a solid?
When heat is removed from a system the heat cools down. If you boil water and you put it in the freezer it will become ice. When heat is added to a system it makes the temperature go up. If you add heat to a solid it becomes a liquid.

Q. What state of matter heats up the fastest?
Phases of matter
| A | B |
|---|---|
| crystalline solids | solids with a regular repeating pattern |
| molecules move fastest in this phase | plasma |
| molecules move faster than liquids in this state | gas |
| molecules move the slowest in this state | solid |
Q. When a solid is heated and turns into liquid is called?
When a solid is heated the particles gain sufficient energy to break away from one another and move past each other. When this occurs the matter is in the liquid state. The change from solid to liquid is called melting or fusion.
Q. What will happen if the beaker is heated until the wax melts?
Show the pupils the beaker containing the mixture of gravel and chopped candlewax before heating; ask what will happen if the beaker is heated until the wax melts. Most will realise that the gravel will sink to the bottom to form a mixed gravel/wax layer, whilst pure wax will flow to the top to form another layer.
Q. What happens when a liquid is heated Class 9?
What happens when a liquid is heated? As its temperature increases, the molecules of the liquid gain energy and their kinetic energy increases. As the kinetic energy increases, the molecular motion increases and the molecules of the liquid overcome the force of attraction between them.
Q. Is evaporation and boiling the same thing?
Boiling happens to all of a liquid at once and occurs only when a liquid is heated to one specific temperature, it’s boiling point. Evaporation can happen in a liquid at any temperature below the boiling point of the liquid, but it can only happen to the particles at the surface of the liquid.
