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...
Melting and freezing are opposite processes. Melting is the occurrence wherein a solid substance changes to a liquid state. On the other hand, freezing is the change form a liquid state to a solid state. Both processes, however, involve a certain amount of heat in order to proceed....
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. Melting of Ice: When ice (solid state of water) is heated, it melts and turns into liquid water. This is a physical change because the chemical composition of water (H₂O) remains the same.2. Evaporation of Water: When the liquid water is heated further, it evaporates and becomes...
