Particles in a solid have the least amount of energy. TRUE or FALSE 2. Particles in a gas are very attracted to each other. TRUE or FALSE 3. A liquid does not take the shape of its container. TRUE or FALSE 4. Heat is (a) hot (b) energy (c) cold 5. Temperature is (a) How hot a liquid is (b) How cold a substance is (c) How we measure heat 6. Water boils at 100℃ so explain why a cup of tea has an approximate temperature of 80℃. 7. Explain what happens to the particles inside a thermometer when they go from 80℃ to 10℃.
Understand the Problem
The question presents a series of statements and queries related to the properties of matter, specifically solids, liquids, and gases, as well as concepts of heat and temperature. The aim is to assess understanding of these topics, including particle behavior and energy changes.
Answer
1. TRUE 2. FALSE 3. FALSE 4. (b) energy 5. (c) How we measure heat 6. Environmental heat loss reduces the temperature. 7. Decreased kinetic energy results in less particle movement.
- TRUE 2. FALSE 3. FALSE 4. (b) energy 5. (c) How we measure heat 6. A cup of tea typically has an approximate temperature of 80°C due to heat loss to the surrounding environment. 7. As temperature decreases from 80°C to 10°C, particles inside the thermometer lose kinetic energy and move less vigorously.

More Information
Matter can exist in different states with varying particle energy. Understanding thermal dynamics is key to explaining temperature changes in everyday life.
Tips
- Don't confuse interparticle forces across different states of matter. 2. Remember that liquids take the shape of their containers.
