FAQs on Changes in States of Matter Video Lecture - Chemistry for Class 9
| 1. What are the three states of matter? |  |
Ans. The three states of matter are solid, liquid, and gas.
| 2. What is a phase change? | |
Ans. A phase change is a physical change in which a substance transitions from one state of matter to another. For example, when ice melts into water, it undergoes a phase change from a solid to a liquid.
| 3. What is sublimation? | |
Ans. Sublimation is the process in which a substance transitions directly from a solid to a gas, without passing through the liquid state. An example of this is dry ice, which sublimates at room temperature.
| 4. What is the difference between evaporation and boiling? | |
Ans. Evaporation is the process in which a liquid turns into a gas at a temperature below its boiling point, while boiling is the process in which a liquid turns into a gas at its boiling point.
| 5. How does temperature affect the states of matter? | |
Ans. Temperature affects the states of matter by determining the amount of energy that particles have. As temperature increases, particles gain energy and move more quickly, causing a substance to transition from a solid to a liquid and then to a gas. Conversely, as temperature decreases, particles lose energy and move more slowly, causing a substance to transition from a gas to a liquid and then to a solid.
