Solution

According to Charles's Law, the volume of a gas is directly proportional to its temperature, assuming the pressure is kept constant. This means that as the temperature increases, the volume of the gas also increases.

So, if a blown balloon is left inside a car at noon on a hot summer day, the air inside the balloon will heat up. As the temperature of the air inside the balloon increases, the volume of the balloon will also increase.

The pressure inside the balloon is determined by the elasticity of the balloon material and the amount of air inside it. As the balloon expands, the pressure inside the balloon will remain roughly constant, assuming the balloon doesn't burst.

So, the correct answer is D: the balloon's volume increases, while the balloon's pressure remains constant.

Select which of the following would happen if you blew up a balloon at room temperature and then put it in the freezer for 10 minutes. he balloon would increase in size as the particles would slow down in motion and expand. The balloon would decrease in size as the particles would slow down in motion and contract. The balloon would decrease in size as the particles would increase in motion and contract. The balloon would stay the same size as the movement of particles would stay the same.

A balloon with the volume of 24.0 L and at 23 °C and pressure of 1.00 atm is let go. The balloon after 20 minutes reaches a much higher elevation where due to lower pressure of 0.500 atm is now expands to 28.0 liters. What is the temperature at that elevation in Celsius degrees?  [Hint: combined gas law requires temperature input in kelvin and produces results also in kelvin].
