Problem 1Hydrogen gas contracts at constant pressure from 1.00 L to 0.95 L. The initial temperature is 20 °C. Find the final temperature of the gas? Problem 2Carbon dioxide gas expands from 10.0 cm3 to 11.5 cm3. The final temperature is 45 °C. Determine the initial temperature if the expansion is isobaric? Problem 3The temperature of a gas changes from 25 °C to 80 °C. The final volume is 100 mL. Find the initial volume? Problem 4During transport of steam from one industrial vessel to another, temperature drops by 5 °C. The initial temperature is 120 °C. Assume the pressure remains constant. Find the final volume if the initial volume is 4.0 m3? Problem 5The volume of oxygen gas at 25 °C is 10 m3. If the volume of the gas is double, what will be its new temperature? Problem 6The volume of a balloon of helium is 0.75 L in Los Angles. The temperature in Log Angles is 13 °C. Find the volume of the balloon in Death Valley where the temperature is 51 °C? The pressure is constant at both places. Los Angles to Death ValleyProblem 7A gas occupies 22.2 mL at a temperature of 358 K. Find the new volume if the temperature is reduced to 220 K? Problem 8A student collects an experimental gas of a volume of 730 mL at 84 °C. What will be the temperature at 700 mL if the pressure is constant? Problem 9A sealed syringe dipped in icy water at a temperature of −12 °C. The volume of the air in the syringe at room temperature (20 °C) is 53 mL. What is the volume in the icy water? Problem 10An experiment is performed on a gas under constant pressure to studies its behaviour. The volume-temperature data for a fixed amount of the gas is recorded. The data is as follows: Volume vs temperature experimental data

What is Charles Law Short answer?Charles's law, a statement that the volume occupied by a fixed amount of gas is directly proportional to its absolute temperature, if the pressure remains constant.
How do you calculate Charles Law?Based on the definition of Charles' law, we can write the Charles' law equation in the following way: V₁ / T₁ = V₂ / T₂ , where V₁ and T₁ are the initial volume and temperature, respectively. Similarly, V₂ and T₂ are the final values of these gas parameters.
