Read through this website. For each substance – water, copper, and nitrogen – find out how the molecules are moving
in hot, war, and cold temperatures, and describe how the molecules are moving. Use the space below each question for
your answer; use the back of the sheet if necessary.
Click the water button
1. Choose a cold region on the thermometer. Is water a solid, liquid, or gas? What is the temperature? Describe how
the molecules are moving. (Be specific)
2. Choose a warm region on the thermometer. Is water a solid, liquid, or gas? What is the temperature? Describe
how the molecules are moving. (Be specific)
3. Choose a hot region on the thermometer. Is water a solid, liquid, or gas? What is the temperature? Describe how
the molecules are moving. (Be specific)
