S3.8.4 For the adult
Heat and temperature
Which holds more energy, a cup of boiling water or a bath of warm water?
What this chapter teaches
Temperature tells how hot something is. Heat is energy moving from hotter to cooler things. A large amount of warm water can hold more thermal energy than a small amount of hot water.
Three questions to ask
There is no one right wording. Listen for the idea.
- Which way does energy move when a hot cup stands in a cool room?
- Why can a bath of warm water hold more thermal energy than a cup of boiling water?
- How do you read a thermometer when the liquid stops between two numbers?
After the chapter, the learner can
- Explain the difference between heat and temperature
- Read a thermometer and record temperatures in degrees Celsius
What they copy into their notebook
Temperature tells how hot a thing is, in °C. Heat is energy moving from hot to cool. Thermal energy depends on temperature and on how much there is.
