Name:
1. State each of the following laws (don’t just write the formulas): a) Boyle’s law: b) Charles’s law: c) Gay-Lussac’s law: d) Avogadro’s Principal: 2) If you increase the volume of a gas but keep the temperature constant, what will happen to the pressure of the gas? 3) If you increase the temperature of a gas but keep the volume constant, what will happen to the pressure of the gas? 4) If you increase the pressure on a gas but keep the volume constant, what will happen to the temperature of the gas? 5) You have a 5.0 L of gas at 450 mmHg. If the pressure of the gas is increased to 760 mmHg, what will the volume of the gas be? Law used:
Solution:
6) A gas is confined in an expandable container of 6.0 L at a temperature of 54oC. If the gases is heated to a temperature of 65oC, what will the volume of the container expand to? Law used:
Solution:
7) A gas is under a pressure of 1 atm and a temperature of 19oC. What will the pressure of the gas have be if the temperature reaches 232oC? Law Used:
Solution:
8) A gas is under a pressure of 7 atm in a 4.00 L container. Its temperature is 35oC. What will the volume have to be reduced to change the gas’s pressure to 14 atm and 27oC? Law used:
Solution:
9) How many moles of nitrogen can be contained in a 10.0 L container at a pressure of 5.4 atm, a temperature of 25oC? Law used:
Solution:
10) What pressure will 4.5 moles of hydrogen gas be under in a 3.00 L container at 37oC? Law used:
Solution:
13) How are ideal gases different than real gases? 14) How many liters of gas do you have if you have 4.9 moles of gas? 15) Convert 29oC to Kelvin. 16) What is the value of R when pressure is measured in atmospheres? 16) Why is a tire blowout more likely on a hot summer day than a cold winter day? (think in terms of volume and pressure)
17) What is the density of O2 at STP? 18) A gas with a density of 0. 179 g/L has what molar mass at STP? 19) What is the density of SF4 at 0.855 atm and 100oC? 20) What is the molar mass of a gas that has a density of 1.25 g/L at 25oC and 0.955 atm?
22) In the reaction 2H2 + O2 → 2H2O, how many Liters of oxygen would react completely with 6.4 L H2 at STP? 23) Using the same equation in # 22, how many grams of water would be produced from 3.00 L of oxygen at 25oC and 1.5 atm?
