Answer:
a) Melting: An example of melting in everyday life is when an ice cube placed on a warm surface starts to melt and turns into liquid water. Melting is the process in which a solid substance absorbs enough heat energy to transition into a liquid state. The heat energy breaks the bonds holding the particles of the solid together, causing them to gain enough kinetic energy to move more freely and transition to a liquid form.
b) Freezing: Freezing can be observed when water is placed in a freezer and transforms into ice. Freezing is the reverse process of melting. It occurs when a liquid substance loses heat energy and its particles slow down, leading to the formation of a solid structure. The decrease in temperature causes the particles to arrange themselves into an organized pattern, creating a solid state.
c) Condensation: When you see water droplets forming on the surface of a cold beverage on a hot day, that is an example of condensation. Condensation is the process by which a gas or vapor cools down and transforms into a liquid state. It happens when the temperature of the gas or vapor reaches a point where its particles lose enough energy to come together and form liquid droplets.
d) Evaporation: When wet clothes or a puddle of water dries up after exposure to sunlight or air, it is an example of evaporation. Evaporation is the process by which a liquid substance, such as water, turns into a gas or vapor. It occurs when the particles near the surface of the liquid gain enough energy from the surroundings to break free from the liquid phase and enter the gaseous phase.
e) Sublimation: An example of sublimation is the direct conversion of solid dry ice (frozen carbon dioxide) into a gas without passing through a liquid phase. Sublimation is the process in which a solid substance transforms directly into a gas without going through the intermediate liquid phase. It occurs when the substance absorbs enough heat energy to break the bonds between its particles, causing them to transition from a solid state to a gaseous state.
