Homework Assignment #5 States of Matter Gases, Liquids and Solids (Due date: October 29, 2019) (I) Consider the following sample of gases: = He N2 (i) (ii) (iii) If the three samples are all at the same temperature, rank them with respect to (a) total pressure; (b) partial pressure of helium; (c) density: (d) average kinetic energy of particles. (II) The temperature of a gas is raised from 10 °C to 20 °C. Will the volume double if mass and pressure do not change? Why or why not? (Show your calculations) (III) If 3.25 L of gas at 16.0 °C and 1.00 atm is compressed at a pressure of 125 atm at 20.0 °C, calculate the new volume of the gas. (IV) Calculate its volume (in liters) of 88.4 g of CO; at STP (V) H2O and CH4 are gases at 150 °C. Which exhibits more ideal behavior? Why? (VD Assume that you have a cylinder witha movable piston. What would happen to the gas pressure inside the cylinder if you were to do the following? (a) Triple the Kelvin temperature while holding the volume constant (b) Reduce the amount of gas by 1/3 while holding the temperature and volume constant (c) Decrease the volume by 45 % at constant T (d) Halve the Kelvin temperature, and triple the volume
