Chapter 14 Test Review: Gas Laws

Front

What is the relationship between the volume of a gas (V) and its absolute temperature (T) when pressure is held constant?

Back

According to Charles's Law, the volume of a gas is directly proportional to its absolute temperature when pressure is constant.

Front

How do you convert Celsius to Kelvin?

Back

To convert Celsius to Kelvin, add 273.15 to the Celsius temperature.

Front

What is 50°C in Kelvin?

Back

50°C is 323 K.

Front

What is the basis of kinetic-molecular theory?

Back

The basis of kinetic-molecular theory is that molecules are in constant motion.

Front

What happens to the pressure of a gas in a flexible container as the volume increases?

Back

As the volume increases, the pressure decreases.

Front

If a gas is at a higher pressure, what can be inferred about its temperature compared to a gas at lower pressure in equal volume containers?

Back

The gas at higher pressure is at a higher temperature.

Front

What is Boyle's Law?

Back

Boyle's Law states that the pressure of a gas is inversely proportional to its volume when temperature is held constant.

Front

What happens to the volume of a gas if the temperature decreases while pressure remains constant?

Back

The volume of the gas decreases.

Front

Define absolute zero.

Back

Absolute zero is the theoretical temperature at which a substance has minimum thermal energy, equivalent to 0 K or -273.15°C.

Front

What is the ideal gas law equation?

Back

The ideal gas law is represented by the equation PV = nRT, where P is pressure, V is volume, n is the number of moles, R is the gas constant, and T is temperature.
