A 30 ml sample of gas is at 557 K and has a pressure of 7 atm. If the temperature is changed to 283 K and 3 atm, the new volume of the gas in liters would be........

• 0.036L

• 0.36L

• 0.0036L

• 3.60L

Solids have a definite shape and volume, this is because.....

• the molecules in solids move past each other easily

• the molecules in solids stay in a definite location and vibrate

• the molecules in solids move freely in all directions

• the molecules in solid do not move at all

At constant pressure which graph shows the correct relationship between volume (V) of a gas and it's absolute temperature (T)?

• A

• B

• C

• D

Given an unknown quantity of gas at a pressure of 2.2 atm, a volume of 70 liters and a temperature of 86^oC, how many moles of gas are present?

• 10.23 moles

• 154 moles

• 30 moles

• 5.23 moles

The kinetic molecular theory assumes that particles of an ideal gas

• are in random, constant, straight line motion

• are arranged in a regular geometric pattern

• have strong attractive forces between them

• have collisions that result in the system losing energy
