Heating Matter Matterca

There are three states of matter – solids, liquids and gases. Matter can change from one state to another when heat is added or taken away. When solid matter is heated, it changes from a solid to a liquid. Ice is a solid. When ice is heated it changes into liquid water. This process of changing from a solid to a liquid is called melting. A candle is made of solid wax. When you light a candle, the heat from the flame causes the solid w wax to melt into liquid wax.

What are some other examples where heat causes a solid to melt into a liquid?

Evaporation

When liquid matter is heated, it changes into a gas. This process is called evaporation. d When it rains, puddles of water form on the ground. As the heat from the Sun warms the water, the puddles get smaller. A puddle gets smaller because the water evaporates into the air as a gas called water vapor. Eventually, all of the water evaporates into the air and the puddle dries up. . When water is heated to a high temperature, it boils. The bubbles you see in a pot of boiling water are pockets of gas. The bubbles of gas move to the surface of the water and into the air as water vapor. s i n. e water nto How will liquid matter change when it is heated? ou se f ga face of t d ee s. he e in The The e w ew ducation
