If average for 3 = 84 then sum for 3 = 84*3 = 252.

If average for 4 = 88 then sum for 4 = 88*4 = 352

so required score in quiz 4 = 100.

Why does an increase in temperature increase the volume of a balloon?

This requires one simple equation and then a further understanding of it. PV=nRT where P is pressure, V is volume, T is temperature, n is the number of molecule, R is some constant. From this we can easily see that an increase in temperature does in fact cause an increase in volume. To see why lets think about what temperature is. Temperature is a measure of average kinetic energy. So an increase in temperature increases the average kinetic energy. An increase in average kinetic energy means that average velocity must be increased (K.E = .5(mv^2)). More velocity means that the molecules in the balloon are flying faster, and since pressure is the same, the molecules spread out more, which must increase the volume.
