All matter exists as solids, liquids, or gases. These are called the states of matter. 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.
What is Change of state

Speed
What is What is each of the possible gear ratios of a bicycle or motor vehicle.
300
a stable subatomic particle occurring in all atomic nuclei, with a positive electric charge equal in magnitude to that of an electron, but of opposite sign
What is Proton
300
transfer
What is The conversion of one form of energy into another, or the movement of energy from one place to another. Solar panels allow for energy transfer from light energy to heat and electrical energy
