suppose a balloon is filled with air. How would the volume of the air in the balloon change with an increase in temperature?

Can someone help explain this to me and what does the particles of matter have to do with this?

2.) How would the volume of the air in the balloon change with a decrease in temperature?

5.) How would the mass of the air in the balloon change with an increase in temperature?

12.) How would the mass of the air in the balloon change with a decrease in temperature?

Charles' Law says that the volume of a gas is directly proportional to the temperature. Said another way, if the T increases, volume increases; if T decreases, volume decreases. That should give you (2).
5) and (12). The mass is not affected. Unless you add more air or open the end to let air out, the mass of the air will not change.
