shutting up will help if that's what you are trying to do tell your mommy that!
According to the textbook "Heating and Cooling Essentials" When a solid changes to a liquid or vice versa, it is simply called "change of state".
Let's consider the case of ice. Ice is a solid. When heated, it gets transformed to water. Water is a liquid. Further heating changes water into gas. Thus, heat can change a solid into both liquid and solid form.
Some solids are Carbon dioxide, Snow, Iodine and Naphthalene
KEY: - to make into = this is what you do solid - liquid = melting solid - gas/gas - solid = sublimation liquid - solid = freezing liquid - gas = evaporation gas - liquid = condensation They all involve heating up or cooling down the state. Hope this helps(:
Solid, liquid and gas will expand on heating. One exception is water that expands on being heated, and on being frozen into solid ice.
change of a liquid to a solid
Ice (solid water) changes to liquid water when heated. Wax solid changes to liquid wax when heated. Metal becomes molten when heated to its melting point. Paraffin wax solid changes to liquid paraffin wax when heated.
When water freezes it changes from a liquid to a solid. When water boils or evaporates it changes from a liquid to a gas.
The phase changes of matter are melting (solid to liquid), freezing (liquid to solid), vaporization (liquid to gas), condensation (gas to liquid), sublimation (solid to gas), and deposition (gas to solid). These transitions occur due to changes in temperature and pressure.
When a substance changes from liquid to solid is called freezing.
The process in which a solid changes to a liquid is called melting.
These changes of state are: solid to liquid, liquid to gas, gas to liquid, liquid to solid, solid to gas, gas to solid. The majority of substances have these state of matter changes.
