Gas Law calculation (final version

What type of relationship is Charles' Law?

• Inverse
• Direct
• Not enough information
• #goals

In order to solve gas law calculations, temperature must be measured in:

• Fahrenheit
• Celsius
• Kelvin
• It doesn't matter 

A balloon with a volume of 200 mL at 30 ^οC is submerged in hot water to obtain a temperature of 50 ^οC.  What will happen to the volume of the balloon if the pressure remains the same?

• the volume of the balloon will become higher than 200 mL
• the volume of the balloon will become lower than 200 mL
• the volume of the balloon will stay the same
• there is no enough data

What is 50 C in Kelvin?

• 223
• 323
• 100
• 50

The volume of a gas at 25^ο C is 3.8 L.  What will be the volume of that gas at 57 ^ο C if the pressure is held constant?

• 8.66 L
• 4.21 L
• 6.34 L
• 3.46 L

A gas with a volume of 400 mL at 120 ^οC is heated until its volume is 700 mL. What is the new temperature ( in degree Celsius) of the gas if the pressure is constant? (remember to go BACK to Celcius at the end)

• 4 14.75 ^οC

• 687.75 ^οC

• 210 ^οC

• 68.57 ^οC

The volume of a gas at 25^ο C is 3.8 L.  What will be the volume of that gas at 57 ^ο C if the pressure is held constant?

• 8.66 L
• 4.21 L
• 6.34 L
• 3.46 L

Bill Belichick uses a lot of hairspray to keep his hair looking good while coaching an entire game. If his can of hairspray has an initial temperature of 22°C and a pressure of 18.5 atm, what would be the final temperature of the gas is the pressure decreases to 16.9 atm after use?

• 291.5 K

• 289.9 K

• 275 K

• 269 K

The oxygen tanks on the sideline can be very dangerous if heated. Suppose an oxygen tank has a pressure of 120 atm at a room temperature of 25°C. If the temperature on the turf or field increases to 51°C, what will the resulting pressure of the oxygen tank be if the volume and amount of gas does not change?

• 130 atm
• 804 atm
• 1.30 atm
• 254 atm

Waiting to play the Broncos, the Patriots notice the change in the barometric pressure that occurs when arriving in Denver, CO. In Boston, if the temperature is 25°C at a barometric pressure of 101.3 kPa, what would the temperature of the air be if the barometric pressure decreased to that of Denver’s; 84.0 kPa?

• 175 K
• 247 K
• 247 L
• 28.5 K
