Gas Laws Review Warmup

What is the formula for Boyle's Law?

• P1V1 = P2V2

• P1 + V1 = P2 + V2

• P1V1 + P2V2 = 0

• P1/V1 = P2/V2

What is the ideal gas law?

• 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 in Kelvin.

• PV = nR/T, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Celsius.

• PV = nRT^2, where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Fahrenheit.

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

What is Boyle's Law?

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

• Boyle's Law states that the pressure of a gas is inversely proportional to its volume when the temperature is held constant. (P1V1 = P2V2)

• Boyle's Law states that the volume of a gas is constant regardless of pressure changes.

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

What is Avogadro's Law?

• Avogadro's Law states that equal volumes of gases, at the same temperature and pressure, contain an equal number of molecules.

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

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

• Avogadro's Law states that the mass of a gas is directly proportional to the number of molecules present.

What is Charles' Law?

• Charles' Law states that the volume of a gas is directly proportional to its temperature (in Kelvin) when pressure is held constant. (V1/T1 = V2/T2)

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

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

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

What is the significance of absolute zero in gas laws?

• It is the temperature at which a gas has zero volume and pressure.

• It is the temperature at which gases behave ideally.

• It is the temperature at which all molecular motion stops.

• It is the temperature at which gases can be compressed indefinitely.

What happens to the volume of a helium balloon when placed in a freezer?

• The balloon's volume increases due to the decrease in temperature.

• The balloon's volume remains the same regardless of temperature changes.

• The balloon's volume decreases due to the decrease in temperature.

• The balloon pops due to the cold temperature.

What is the Combined Gas Law?

• The law that states that the pressure of a gas is inversely proportional to its volume at constant temperature.

• The law that combines Boyle's, Charles', and Avogadro's laws and relates pressure, volume, and temperature of a gas. (P1V1/T1 = P2V2/T2)

• The principle that states that the volume of a gas is directly proportional to its temperature at constant pressure.

• The law that describes the behavior of ideal gases under varying conditions of pressure and temperature.

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

• Increasing the number of moles decreases the pressure.

• Increasing the number of moles has no effect on pressure.

• Increasing the number of moles increases the pressure.

• Increasing the number of moles causes the pressure to fluctuate.

How do you convert Celsius to Kelvin?

• K = °C + 273

• K = °C - 273

• K = °C * 273

• K = °C / 273
