pressure, volume, temperature, and number of moles
What are the four measurable properties of gases?
Boyle’s law
states that the volume of a given mass of gas held at constant temperature is inversely proportional to its pressure.
P1V1 = P2V2
What is the standard formula for boyle’s law?
P2 = 250 mmHg
Freon in an air-conditioning unit has a volume of 0.30 liter. It is allowed to function in a room where the pressure is about 750 mmHg, assuming that the temperature is in a constant state. Find the final pressure of Freon when its volume is increased to 0.90 liter.
V2 = 131.25 mL
A sample of a gas occupies a volume of 350 mL under a pressure of 0.75 atm. if the temperature is held costant, what volume will the sample occupy under 2 atm of pressure?
Jacques Alexander Charles
He found out that various gases expanded by the same amount when heated through the same temperature interval.
Charle’s Law
This states that the Kelvin (K) temperature (T) and the volume (V) of a gas are directly related when there is no change in the pressure (P) of a gas.
Temperature increases, the Volume increases
V1 / T1 = V2 / T2
What is the standard formula of Charle’s Law?
V2 = 120.12 mL
A 132 mL of gas is measured at 38 degrees celsius. If the pressure remains constant, what will be the volume of the gas at 10 degrees celsius?
T1 = 537.44 K
A gas has a final volume of 300 mL at 20 degrees celsius. What is the initial temperature if its volume is 550 mL?
