FAQs on MCQ with Solution : Matter in Our Surroundings - Class 9
| 1. What is matter? |  |
Ans. Matter is anything that occupies space and has mass. It can exist in three states, namely solid, liquid, or gas.
| 2. What is sublimation? | |
Ans. Sublimation is the process of changing a solid directly into a gas without passing through the liquid state. An example of sublimation is the process of dry ice (solid carbon dioxide) changing into gas on exposure to normal room temperature.
| 3. What is the difference between evaporation and boiling? | |
Ans. Evaporation is the process of changing liquid into a gas at any temperature below the boiling point. Boiling, on the other hand, is the process of changing liquid into a gas at a specific temperature called the boiling point.
| 4. What is the role of intermolecular forces in matter? | |
Ans. Intermolecular forces are the forces of attraction and repulsion between molecules. They determine the physical properties of matter, such as melting point, boiling point, and viscosity. The strength of intermolecular forces varies between different states of matter, with solids having the strongest intermolecular forces and gases having the weakest.
| 5. Why does the boiling point of water decrease at high altitudes? | |
Ans. The boiling point of water decreases at high altitudes because the atmospheric pressure decreases with altitude. The boiling point of a liquid is the temperature at which its vapor pressure is equal to the atmospheric pressure. At high altitudes, the atmospheric pressure is lower, so the vapor pressure of water at its boiling point is also lower, and hence, it boils at a lower temperature.
