Front

Inversely proportional means as one value increases the other...

Back

decreases.

Front

What is the pressure of a car tire that had an initial pressure of 1.8 atm but was heated from 38°C to 123°C?

Back

2.9 atm

Front

The gas in an aerosol can exerts a pressure of 3.00 atm at 25°C. What would the gas pressure in the can be at 100°C?

Back

4.1 atm

Front

What is standard pressure?

Back

1 atm

Front

What is standard temperature?

Back

273 K

Front

What is Boyle's Law?

Back

At constant temperature, the pressure of a gas is inversely proportional to its volume.

Front

What is Charles's Law?

Back

At constant pressure, the volume of a gas is directly proportional to its temperature in Kelvin.

Front

What is the Ideal Gas Law?

Back

PV = nRT, where P is pressure, V is volume, n is number of moles, R is the gas constant, and T is temperature in Kelvin.

Front

What is the gas constant (R) in the Ideal Gas Law?

Back

0.0821 L·atm/(K·mol) or 8.314 J/(K·mol).

Front

What happens to gas pressure when the volume decreases at constant temperature?

Back

The pressure increases.
