Why is the melting of ice not a chemical reaction? Why does temperature remain constant for melting ice? Why is the freezing of water called a physical change? Why does increasing the temperature of a solid make it melt? Why is condensation a physical change?
1. Ice melting involves a change from a solid to a liquid and the substances maintain the properties of water because the molecules never change. 2. Water boiling is a physical change as water molecules vibrate faster, they enter the gas phase and become water vapor. 3. Rubbing alcohol left...
