A student Increases the temperature of a 417 cubic centimeter balloon from 278 K to 231 K. Assuming constant pressure what should the new volume of the balloon be

Initial Conditions:

Volume = v1 = 417 cm³

Temperature = T1 = 278 K

Final Conditions:

Temperature = T2 = 231K

Volume = v2 = ?

Use the general gas equation;

P1*v1/T1 = P2*v2/T2

As, the temperature is constant;

So,

v1/T1 = v2/T2

417/278 = v2/231

v2 = 346.5 cm³
