A stone of mass 13 kg is dropped into a tank of water from just above the watersurface. The tank contains 100kg of water which is 1.3m deep. The stone has aspecific heat of 1000 J/kgK and water 4200 J/kgK. If the water and stone are initiallyat the same temperature, determine the temperature rise f the water. State anyassumptions made answer: 3.8x10^-4K

a sphere emissivity = 0.42 of radius 25 cm is at 27 degrees celsius is placed in a room with a temperature of 2 degrees celsius A. what is the rate of heat energy enterinh the sphere B. How long will it take for the spiritual as 1 x 10^6 joules of energy?

Heat transfers from your lungs and breathing passages by evaporating water. (a) Calculate the maximum number of grams of water that can be evaporated when you inhale 1.50 L of 37ºC air with an original relative humidity of 40.0%.(Assume that body temperature is also 37ºC .)                                                    (b) How many joules of energy are required to evaporate this amount?            (c) What is the rate of heat transfer in watts from this method, ifyou breathe at a normal resting rate of 10.0 breaths per minute?
