- On the next left page, reflect on the following:
- Glass is an amorphous solid. How can you use that information to help explain why a glassblower can bend and shape a piece of glass that has been heated?
Today’s Topic & Question
- How are volume, temperature, and pressure of a gas related?
- Gases are able to easily compress
- In a helium tank, the amount of helium you get actually depends on the temperature and air pressure that day!
- Amount of space matter fills
- Volume of a gas = volume of the container
- Measure of the average energy of motion of the particles in a substance
- Fast particles = greater energy = higher temp.
- Force of its outward push on the walls of the container
- Measured in kilopascals (kPa)
Question for You
- What are 3 properties of a gas you can measure?
Relating Pressure & Volume
- When the pressure of a gas increases, its volume decreases. When the pressure of a gas decreases, its volume increases.
Relating Pressure & Temperature
- When the temperature of a gas increases, its pressure increases.
- When the temperature of a gas decreases, its pressure decreases.
Relating Volume and Temperature
- When the temperature of a gas increases, the volume increases.
- When the temperature of a gas decreases, the volume decreases.
