Answer to relevant QuestionsExplain how the Thermos bottle shown in Fig. 11.17 can minimize all mechanisms of heat transfer. A hot steel ball is dropped into a cold aluminum cup containing some water. ( Assume the system is an isolated.) If the ball loses 400 J of heat, what can be said according to calorimetry? A 0.20-kg glass cup at is filled with 0.40 kg of hot water at 90 oC. Neglecting any heat losses to the environment, what is the equilibrium temperature of the water? In a calorimetry experiment, 0.50 kg of a metal at 100oC is added to 0.50 kg of water at in an aluminum calorimeter cup. The cup has a mass of 0.250 kg. (a) If some water splashed out of the cup when the metal was added, ...Atypical NBA basketball player will do about 3.00 x 106 J of work per hour. Express this work in Calories.
