Combined Gas Law Review

Front

What is the Combined Gas Law?

Back

The Combined Gas Law relates the pressure, volume, and temperature of a gas. It is expressed as (P1V1)/T1 = (P2V2)/T2.

What happens to the volume of a gas when its temperature increases at constant pressure?

Back

The volume of a gas increases when its temperature increases at constant pressure, according to Charles's Law.

Front

What is the formula to convert Celsius to Kelvin?

Back

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

Front

What is STP in terms of temperature and pressure?

Back

STP (Standard Temperature and Pressure) is defined as 0 degrees Celsius (273.15 K) and 1 atmosphere (ATM) of pressure.

Front

If the pressure of a gas increases, what happens to its volume at constant temperature?

Back

If the pressure of a gas increases, its volume decreases at constant temperature, according to Boyle's Law.

Front

What is the relationship between pressure and temperature in a gas?

Back

The pressure of a gas increases with an increase in temperature when volume is held constant, according to Gay-Lussac's Law.

Front

What is the significance of absolute zero in gas laws?

Back

Absolute zero (0 K) is the theoretical temperature at which a gas has zero volume and pressure, and molecular motion stops.

Front

How do you calculate the new volume of a gas when its temperature changes?

Back

Use the formula V2 = V1 * (T2/T1) when pressure is constant.

Front

What is the effect of increasing the number of gas particles on pressure?

Back

Increasing the number of gas particles increases the pressure if the volume and temperature remain constant.

Front

What is the ideal gas law equation?

Back

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