An air bubble at the bottom of a lake 34.5 m deep has a volume of 1.00 cm3.If the temperature at the bottom is 2.3 ∘C and at the top 20.6 ∘C, what is the radius of the bubble just before it reaches the surface?
Two rooms, each a cube 4.4 m per side, share a 12-cm-thick brick wall. Because of a number of 100-W lightbulbs in one room, the air is at 30 ∘C, while in the other room it is at 9.0 ∘C.How many of the 100-W bulbs are needed to maintain the temperature difference across the wall?
