Heat depends only on how fast molecules vibrate.2. Joule is a unit of heat energy.3. We measure temperature with a thermometer.4. The faster molecules vibrate, the more heat they give off.5. Temperature measures the average kinetic energy per molecule.
Answer (1)
Answer:Here are the answers to the questions, based on the provided search results: Activity 1: - (6) Heat - This is implied by the context of the questions.- (7) Calories or Joules - Both are units of heat energy. [[1, 2, 3]]- (8) Energy - Heat is a form of energy.- (10) Temperature - This is implied by the context of the questions.- (11) Degrees Celsius (°C), Degrees Fahrenheit (°F), or Kelvin (K) - These are common units for measuring temperature. [[1, 2, 3]]- (12) Expands - When matter is heated, its molecules move faster and spread out, causing it to expand. Activity 2: 1. FALSE - Heat depends on both the speed of molecular vibration and the number of molecules. [[2, 3]]2. TRUE - Joule is the standard unit of energy, including heat energy. [[1, 2, 3]]3. TRUE - Thermometers are used to measure temperature. [[1, 2, 3]]4. TRUE - Faster vibrating molecules have more kinetic energy, which translates to more heat. [[2, 3]]5. TRUE - Temperature is a measure of the average kinetic energy of the molecules in a substance. [[1, 2, 3]]
