For example, ice melting is an example of a phase change from a solid (ice) to a liquid (water). Phase changes involve changes in energy. Which of the statements regarding phase changes are true? Deposition is the conversion of a gas to a solid. Melting is the conversion of a solid to a liquid. Sublimation is the conversion of a gas to a solid. Freezing is the conversion of a gas to a liquid.

Answer 1

Phase changes are transition between solid, liquid and gas phases, for escample, ice melting is an example of Phase change from solid cice) to liquid Ceweeter). Phase changes involve changes in energy - which of the statements regarding phase changes are true. => correct option is . (1) & (2) i.e. is Deposition is the conversion of gas to solid. 2) melting is the convession of solid to liquid. Explanation. These two statements are true regaading phase. changes. remaining & get and 4th statements are fulse because. 3) sublimation is the conversion of solid to gas. - not a gas to solid. a) freezing is the conversion of liquid to solid. s not a gas to liquid. 5012–) classify cuch Pheese change as escothermic endothermic or niether escothermic or endothermic =s. Exothermic Endothermic . Neither Condensation melting deposition vaporization freezing Sublimcetion

Eseplnation ! 1) Erw.thermic recetion's - The process in which released energy from system to its sumoundinags called escothermic process. lie. Heat is evolved. a) condensation change of water gaseous to liquid. 1.2. water vapor to liquid water culled condensation It is escothermic process. b) Deposition - Change of gas to solid called deposition, It is escthermic process s freezing the conversion of liquid to solid. they called freezing It is escothermic process. 2) Endothermic process, The process in which absorbed energy from System to its Sumoundings is called endothermic processine, B Heat is absorbed. ay melting. The conversion of solid to liquid is cauled melting. It is endothermic process by vaporization in conversion of substance from liguid or solid into gaseous i.e. vapour phtese is called vaporization. It is endothermic process. C/ Sublimation conversion of substance from solid to directly gas Phase is called sublimation. It is endothermic process.
