Boyles, Charles & Combined Gas Laws review

How do you convert Celsius to Kelvin?

• Add 273.15 to the Celsius temperature.

• Subtract 273.15 from the Celsius temperature.

• Multiply the Celsius temperature by 1.8 and add 32.

• Divide the Celsius temperature by 100.

What is the relationship between pressure and volume in Boyle's Law?

• Pressure and volume are directly related; as one increases, the other also increases.

• Pressure and volume are inversely related; as one increases, the other decreases.

• Pressure and volume are unrelated; changes in one do not affect the other.

• Pressure and volume are proportional; they change at the same rate.

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

• The volume of the gas increases.

• The volume of the gas decreases.

• The volume of the gas remains the same.

• The volume of the gas fluctuates.

If a gas occupies 2.5 L at 99 kPa, what will be its volume at 101 kPa if the temperature remains constant?

• 2.1 L

• 2.3 L

• 2.5 L

• 2.7 L

What is the absolute zero temperature in Kelvin?

• 0 K

• -273.15 K

• 100 K

• 32 K

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

• The volume of the gas increases.

• The volume of the gas decreases.

• The volume of the gas remains the same.

• The volume of the gas fluctuates.

What is Charles's Law?

• Charles's Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) at constant pressure.

• Charles's Law states that the pressure of a gas is directly proportional to its volume at constant temperature.

• Charles's Law states that the volume of a gas is inversely proportional to its temperature at constant pressure.

• Charles's Law states that the temperature of a gas is directly proportional to its pressure at constant volume.

What is the effect of increasing temperature on gas pressure at constant volume?

• Decreases the pressure of the gas.

• Has no effect on the pressure of the gas.

• Increases the pressure of the gas.

• Causes the gas to expand.

What is the formula to calculate the new volume of a gas when temperature and pressure change?

• P1V1/T1 = P2V2/T2

• PV = nRT

• V = nRT/P

• P1 + P2 = V1 + V2

If the pressure of a gas is doubled, what happens to its volume?

• The volume of the gas is doubled.

• The volume of the gas remains the same.

• The volume of the gas is halved.

• The volume of the gas is increased by 50%.
