Volume of Balloon Unchanged When Pressure Doubled & Temp Changes

[ZiHao]

A balloon is filled with a gas to a certain volume at a certain pressure at 22.0 degrees Celsius. If the pressure exerted on the balloon is doubled. explain what must the temperature ( in degrees Celcius) be so that the volume of the balloon doesn't change.

If the temperature changes, the volume of the balloon will also change. Higher temperature,more energetic therefore more particle collisions, vice versa. So how can the temperature change but the volume of the balloon does not change( according to the questions)? Thanks!

What makes you think that the balloons volume does not change? The volume of the balloon will change as the pressure does.

I moved the thread to our homework section.

So how can the temperature change but the volume of the balloon does not change

The pressure inside and the pressure outside both increase.

What do the words in the problem statement "so that the volume of the balloon doesn't change." mean to you?

Please write down the equation for the ideal gas law. From this equation, if V is constant, what does the temperature have to do if the pressure doubles?

I thought that OP was under the assumption that the volume cannot change. Apologies.
