The Goodyear blimps, which frequently fly over sporting events, hold approximately 1.65_105ft3 of helium.

If the gas is at 24_C and 1.0 atm, what mass of helium is in the blimp?

Consider a small but known volume of metal that has a large thermal conductivity. (a) Since the thermal conductivity is large, spatial temperature gradients that develop within the metal in response to mild heating are small.

Consider a parallel-plate capacitor that is partially filled with a dielectric of dielectric constant k. the dielectric has the same same height as the separation of the plates of the capacitor but fills a fraction f of the area of the capacitor.
