Students will be able to:
- sketch a graph of the pressure-temperature relationship for a gas.
- calculate the pressure or temperature of a gas after a change in conditions.
Materials & Teacher-developed Resources
- Paper, pencils, textbooks, software
- Student handouts
- Balloons, hot plate, 2L coke bottle, ice
- The teacher will ask students to predict what happens to the pressures of a car’s tires in a very hot day
- Also the teacher will ask students to explain why the pilot of a hot air balloon heats the air inside the balloon to make it rise
- Have students try to describe what is happening on a molecular level when the temperature of a closed bottle (containing air) drops suddenly
