# Question

We all have had the experience that a room full of people always feels warmer than when the room is empty. Ten people are in a 4.0 m x 6.0 m x 3.0 m room at 20oC. If each person gives off heat at a rate of about 100 W and there is no heat loss to the outside of the room, what is the temperature of the room after 10 min? At 20oC, the density of air is 1.2 kg/m3 and its specific heat at constant pressure e is 1005 J / (kg ∙ oC).

How much heat is required to melt a 2.5-kg block of ice at 0oC? Atypical NBA basketball player will do about 3.00 x 106 J of work per hour. Express this work in Calories. Ice (initially at 0 oC) is added to 0.75 L of tea at 20oC to make the coldest possible iced tea. If enough ice is added so the final mixture is all liquid, how much liquid is in the pitcher when this condition occurs? The single glass pane in a window has dimensions of 2.00 m by 1.50 m and is 4.00 mm thick. How much heat will flow through the glass in 1.00 h if there is a temperature difference of between the inner and outer surfaces? ...Assuming that the human body has a 1.0-cm-thick layer of skin tissue and a surface area of 1.5 m2, estimate the rate at which heat is conducted from inside the body to the surface if the skin temperature is 34 oC.
