Interpretation:
Based on Charles’s law, the blanks in the table by using the given condition has to be filled.
Concept Introduction:
Charles’s Law tells that the relationship between temperature and volume of a gas. The law states that at constant pressure the volume of a fixed amount of gas is directly proportional to the temperature in Kelvin units. The mathematical expression for the relationship between volume and Kelvin temperature according to the Charles’s law can be shown as follows,

What volume would the balloon occupy at an altitude of 10,700 m, where the air pressure is only 220 mmHg?arrow_forwarddefine the equilibrium constant KP for the chemical equilibrium ofideal-gas mixtures?arrow_forwardWhich of the following correctly explains why the vapor pressure of water has to be included in the calculations? Some of the liquid water evaporates into the gas, and increases the total pressure generated by the trapped gas. As the H2(g) is bubbled up the reaction solution, some of the H2(g) molecules are solubilized by water in the aqueous solution, effectively decreasing the measured pressure above. The pressure contributed by the H2(g) is greater than the measured total pressure because of the contribution of partial pressure of water vapor. The pressure exerted by the evolved H2(g) is reduced because of the co-presence of water vapor, thus Pwater vapor has to be added to Pdry gas. Overview of the experiment:arrow_forward
