The molecules within a sample have a range of energies. Section 5: Boyle’s Law 1. Boyle’s Law describes the (direct / inverse ) relationship of a gas’ pressure to its volume . 2. In order for the Boyle’s Law relationship to be mathematically proportional, which 2 parameters must be held constant as you manipulate the volume or the pressure of a gas? temperature and moles (or particles) Section 7: Charles’ Law 1. Charles’ Law describes the ( direct / inverse) relationship of a gas’ temperature to its volume . 2. In order for the Charles’ Law relationship to be mathematically proportional, which 2 parameters must be held constant, as you manipulate the volume or the temperature of a gas? pressure and particles or moles 3. Charles’ law requires temperatures to be measured in Kelvin. How do you convert °C to K? K = C + 273 Section 8: Gay – Lussac’s Law 1. When the volume of a container is held constant, increasing the temperature of the gas held inside will cause its pressure to increase .

Section 9: Molar Volume 1. Define ideal gas : A gas that obeys all the rules of the kinetic molecular theory. This gas would be at a high temperature and a low pressure. 2. What would Avogadro say about the number of molecules in each balloon below? 1 Liter of H 2 1 Liter of N 2 1 Liter of O 2 Avogadro would say that each balloon has the same number of molecules. 3. The molar volume is the volume occupied by 1 mole of a substance. For a gas at conditions of 0 °C and 1 atm, the molar volume is 22.4 L (don’t forget the units). 4. You have learned that the coefficients in a balanced equation indicate mole ratios. However, in this section you learned that the coefficients can be interpreted another way. How can they be interpreted? As long as all chemicals are gases, the coefficients can be interpreted as volume (liter) ratios. 3. The mixture of atmospheric gases is a solution. 5. No, through examination of glacial ice core samples, scientists know that the structure and composition of the Earth’s atmosphere has not changed significantly through human history. 7. The tires would be wider, so that the pressure exerted by the vehicle is lower. 9.
