1.	4. Give reason : (a) Freezing of water to ice and evaporationof water are physical changes.(b) Burning of a candle is both a physical anda chemical change.(c) Burning of paper is a chemical change.(d) Cutting of a cloth piece is a physicalchange, though it cannot be reversed.
Answer» a) water is in liquid form and ICE is solid so change of state occurs THEREFORE is a physical change. b) burning of candle melts it and chemical properties inside it also changes due to heat so it's a chemical as well as physical change. c) Burning of paper PRODUCES ash and the chemical properties of paer can be identified by the production of ash so it's a chemical change. d) As we know cutting means dividing so in case of CLOTHES it is stretched into pieces, so it's a physical change though the microscopic changes are not observed.
