D. Long answer questions 1. Explain the differences between a solid and a liquid. 2. Describe how water changes into water vapour, 3. What is boiling? How is it different from condensation? 4. Describe how water changes its form from solid to liquid liquid to gas on cooling.
Answers
Answer:
1 answer (A solid is a state of matter that has a definite shape and volume while a liquid is a state of matter that has volume but no definite shape. 2. A liquid takes the shape of the container that holds it while a solid has a shape of its own. ... Solids are strong, tough, elastic, ductile, and flexible while liquids are not. )
Explanation:
2nd answer ( Evaporation happens when a liquid turns into a gas. ... When liquid water reaches a low enough temperature, it freezes and becomes a solid—ice. When solid water is exposed to enough heat, it will melt and return to a liquid. As that liquid water is further heated, it evaporates and becomes a gas—water vapor.)
3rd answer (Boiling refers to the change of phase from liquid to gas. ... The main difference between boiling and condensation is that boiling is the change of a liquid into its vapor phase whereas condensation is the change of vapor into its liquid phase.)
4th answer (When solid ice gains heat, it changes state from solid ice to liquid water in a process called melting. Ice cubes in a cold drink, for example, gradually melt. ... When water absorbs enough heat, it becomes a gas (water vapor). This process is called evaporation.)
