Review Gas Law Check In #1

Which container will have a lower pressure?

• left
• right
• they both have the same pressure
• I don't know

A gas at a volume of 4 liters is at a pressure of 8 Pa. The volume is changed to 16 Liters, what must the new pressure be? Assume temperature is constant.

• 1 Pa

• 12 Pa

• 10 Pa

• 2 Pa

If 200 mL of a gas at 27°C is cooled to -33°C at a constant pressure, the volume will be

• 250 mL
• 204 mL
• 196 mL
• 160 mL

In order to solve gas law calculations, temperature must be measured in:

• Fahrenheit
• Celsius
• Kelvin
• It doesn't matter 

Convert 0* C to Kelvin

• -273 K

• 273 K

• 0 K

• 100 K

Pressure and temperature have a(n) _________ relationship.

• direct

• inverse

• linear

• exponential

The oxygen tanks on the sideline can be very dangerous if heated. Suppose an oxygen tank has a pressure of 120 atm at a room temperature of 25°C. If the temperature on the turf or field increases to 51°C, what will the resulting pressure of the oxygen tank be if the volume and amount of gas does not change?

• 130 atm
• 804 atm
• 1.30 atm
• 254 atm
