Electric current is passed through a copper ball 1 mm in diameter. The ball is submerged in liquid water at atmospheric pressure, and the current is increased until the water boils. For this situation h=5000W/m2 oC. How much electric power must be supplied to the wire to maintain the ball at 114oC?

hurricanes form when warm, moist air from the ocean surface quickly rises into the atmosphere and forms storm clouds and rain. when the clouds are formed, heat is released which warms the cool air in the upper regions of the atmosphere so that the cycle can continue. which two phases of the water cycle are repeated in this process?
