1. False
2.True
3. False
4. False
Explanation:
1. Burning and other changes in matter do not destroy matter. The mass of matter is always the same before and after the changes occur. The law of conservation of mass states that matter cannot be created or destroyed.
2. Because the particles of a liquid are in constant motion, they will collide with one another, and with the sides of the container. This causes evaporation.
3. Evaporation can take place at temperatures below boiling point since the molecules in the liquid have different energies. As the molecules in a liquid collide, some achieve higher energies, allowing them to escape.
4. Matter can change from one state to another if heated or cooled. If ice (a solid) is heated it changes to water (a liquid). This change is called MELTING. If water is heated, it changes to steam (a gas).
