Question

A balloon, whose volume at 23°C is 535 mL, is heated to 46°C. Assuming the pressure and amount of gas remain constant, what is the volume of the balloon at 46°C

Answer 1

Due to the ideal gas law, we have an equation: PV=nRT. So when the pressure and amount of gas are constant, V1/T1=V2/T2. Temperature using the unit of K. So the answer is 535*319/296=576.6 mL.
