Chem isu part 2

Charles's Law states that when pressure is constant, the temperature and volume of a gas are directly proportional. As temperature increases, the gas expands. This law can be applied to phenomena such as hot air balloons and combustion engines. To calculate the final volume of a gas, the formula V1/T1 = V2/T2 is used. In an example, a gas occupying 400 cm³ at 0°C and 780 mmHg is given. By adding the absolute zero (273°C) to find the initial and final temperatures, and using the formula, the final volume is calculated to be 517.21 cm³. Now onto Charles's Law. Charles's Law is the relationship between temperature and the volume of gas mixture. When the pressure is held at a constant, the temperature and volume will be in direct proportion to each other. Opposing it, when the temperature goes down, it tends to contract more. The purpose of the law is to describe how gas expands when under heat. And the formula for this is V1 divided by T1 equals V2 divided by T2. A real life example that relates to Charles's Law is a floating hot air balloon. Using the expansion of a heated gas inside the balloon, it takes up more volume. It allows the hot air balloon to rise. Charles's Law is also applicable to combustion engines. Now to use Charles's Law in a mathematical example. A gas occupies a volume of 400 centimeters cubed at a 0 degree Celsius and 780 millimeters of mercury. How many liters of volume will the gas occupy at an 80 degrees Celsius and 780 millimeters of mercury? Now first you would need to find your initial temperature and your final temperature. To find this, you would need to add the absolute zero, which is 273 degrees Celsius, to both variables. After doing that, your initial temperature should be 273 degrees Celsius and your final temperature should be 253 degrees Celsius. And your volume, which is already given to you, would be 400 centimeters cubed, which leaves our final volume to be found. Then after plugging in your numbers into the equation, you would first need to divide your initial temperature with your final temperature. And after, you would be multiplying it with your initial volume to get your answer of 517.21 centimeters cubed as your final volume.
