Question

write the physical and chemical changes expereinced in incidents in your day to day life

Answer 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.

Water boiling is a physical change as water molecules vibrate faster, they enter the gas phase and become water vapor.

A change can't be both physical and chemical, but physical and chemical changes can occur simultaneously. This is what's happening with the burning candle: the wax is melting, which is a physical change, and it's combusting, which is a chemical change.
