Step-by-step solution for: Heat Vs Temp Worksheet | PDF
Let’s go step by step to fill in the blanks and answer the true/false questions. We’ll use the word bank provided:
Word Bank:
- less heat
- lower temperature
- expand
- how fast molecules vibrate
- degrees
- related
- higher temperature
- Joules
- not
- the number of molecules
- more heat
---
1. Heat and temperature are _related_ but they are _not_ the same.
→ They’re connected, but not identical concepts.
2. Temperature depends upon _how fast molecules vibrate_.
→ Temperature is about average kinetic energy — which relates to speed of vibration.
3. Heat depends on _how fast molecules vibrate_ and also on _the number of molecules_ that vibrate.
→ Heat = total energy, so it depends on both speed AND how many molecules there are.
4. Faster vibrating molecules mean a _higher temperature_.
→ More motion = hotter.
5. Slower vibrating molecules mean a _lower temperature_.
→ Less motion = colder.
6. More vibrating molecules usually mean _more heat_.
→ More particles moving = more total energy (heat).
7. Fewer vibrating molecules usually mean _less heat_.
→ Fewer particles = less total energy.
8. Temperature is measured in units called _degrees_.
→ Like Celsius or Fahrenheit.
9. Heat is measured in units called _Joules_.
→ Energy unit for heat.
10. Heat makes matter _expand_.
→ When things get heated, they usually take up more space.
---
1. Heat comes from vibrating molecules only. → False
→ Heat can come from other forms of energy too (like chemical reactions, friction, etc.), though at molecular level it’s often vibration/motion.
2. Molecules always vibrate at the same speed. → False
→ Their speed changes with temperature.
3. The faster molecules vibrate, the less heat they give off. → False
→ Faster vibration means MORE heat, not less.
4. Temperature measures the average kinetic energy per molecule. → True
→ That’s exactly what temperature is.
5. Temperature is measured in calories. → False
→ Calories measure heat/energy; temperature is in degrees.
6. We measure temperature with a barometer. → False
→ Barometers measure air pressure. Thermometers measure temperature.
7. Heat depends only on how fast molecules vibrate. → False
→ It also depends on how many molecules there are.
8. An ice cube has energy. → True
→ Even cold things have some thermal energy — molecules still move a little.
9. An ice cube has the same amount of energy as a block of ice. → False
→ A bigger block has more molecules → more total heat energy.
10. Heat energy is measured in Joules. → True
→ Yes, Joules are the standard unit for energy including heat.
