In a deep dive, a whale is appreciably compressed by the pressure of the surrounding water. What happens to the whale's density?

Which has more volume-- A kilogram of gold or a kilogram of aluminum?

A block of aluminum with a volume of 10cm^3 is placed in a beaker of water filled to the brim. Water overflows. The same is done in another beaker with a 10 cm^3 block of lead. Does the lead displace more, less, or the same amount of water?

Would it weigh more than an identical bottle with the air pumped out?

What physics concept underlies these three observations? When passing an oncoming truck on the highway, your car tends to sway towards the truck. The canvas roof of a convertible automobile bulges upward when the car is traveling at high speeds. The windows of the older trains sometimes break when a high speed train passes by on the next track.

If the composition of the upper atmosphere were changed so that it permitted a greater amount of terrestrial radiation to escape, what effect would this have on the earth's climate?

How about if the atmosphere reduced the escape of terrestrial radiation?
