Honors U4 Zone 4 Gas Laws Check

What is the definition of pressure?

• Force per unit volume on a surface

• Force per unit area on a surface

• Mass per unit area on a surface

• Volume per unit area on a surface

Which of the following is a unit of pressure used in meteorology?

• kPa

• Celsius

• Meter

• Gram

Match the following temperatures with their standard values in Kelvin.

• Room temperature

• 250 K

• Below freezing point

• 300 K

• Freezing point of water

• 290 K

• Average temperature

• 273 K

Which law is being applied in this example:

Example: Oxygen gas with a partial pressure of 301 mm Hg is mixed in a container with chlorine gas that has a partial pressure of 0.649 atm.  What is the total pressure inside the container, in atm?

• Boyle's Law

• Charles's Law

• Dalton’s Law

• Avogadro's Law

What is the total pressure in atm if the partial pressures are 0.396 atm and 0.649 atm?

• 1.05 atm

• 0.396 atm

• 0.649 atm

• 760 atm

According to Boyle's Law, what is the relationship between pressure and volume?

• P₁V₁ = P₂V₂

• P₁ + V₁ = P₂ + V₂

• P₁/V₁ = P₂/V₂

• P₁ - V₁ = P₂ - V₂

Match the following units with their corresponding examples.

• Pressure measurement in vacuum systems

• Torr

• SI unit of pressure

• Atmospheres (atm)

• Pressure at sea level

• Bar

• Metric unit of pressure

• Pascals (Pa)

How do you convert Celsius to Kelvin?

• K = °C + 273

• K = °C - 273

• K = °C × 273

• K = °C / 273

What is the key concept demonstrated by Charles's Law?

• The relationship between volume and temperature

• The relationship between pressure and volume

• The relationship between mass and volume

• The relationship between temperature and pressure

What happens to the pressure of a gas if the temperature is doubled, assuming constant volume?

• Pressure is halved.

• Pressure remains the same.

• Pressure is doubled.

• Pressure is quadrupled.
