Chapter 13 Review

Gases

• are compressible

• fill the space of their container

• exert pressure to the surface beneath them

• do not have mass

Which of the following is the correct formula and units for pressure?

• Area (m²) / Force (N)

• Force (N) / Area (m²)

• Area (cm3) / Force (N)

• Force (Pa) / Area (m²)

___ is the device used to measure atmospheric pressure.

Using the conversions above, 2.725 atm is equivalent to how many torr?

According to Boyle's Law, doubling the volume cause the pressure to

• double

• quadruple

• reduce to half

• reduce to quarter

According to Charles' Law, halving the temperature causes the volume to

• quadruple

• double

• reduce to half

• reduce to quarter

The coldest temperature known to us, which is 0 K and 273 degrees Celsius is called

What volume (mL) of gas would result if 225 mL of argon gas is compressed from 1.02 atm to 2.99 atm at constant temperature? Round to one decimal place.

Suppose 1.25 L of neon is cooled from 291 K to 78 K. What is the new volume in liters of the sample? Round to two decimal places.

If 2.71 g of argon gas occupies a volume of 4.21 L, what volume (in liters) will 1.29 mol argon occupy under the same conditions? MM of Ar=39.85 g/mol. Round to one decimal.
