- Show all working explaining detailly each step. Imagine you were provided with: a stirrer, a thermometer, a plastic cup, a stand, a piece of plywood with holes in it, through which a thermometer and a stirrer can pass, a large measuring cylinder, some warm water, some cubes of ice, a clean rag. Measure the temperature (θR) of the room. Transfer a known volume (V1) of warm water into the cup that can fill it to about two thirds of its capacity. Keeping the cup open, stir the warm water continuously until its temperature falls down to a value θ1 that is about 5 or 60C above θR. Dry some small blocks of ice with a clean rag and drop them into the warm water. Place the wooden or cardboard lid over the cup, with the stirrer and the thermometer in the holes in it. Stir the water continuously and put just enough small blocks of ice in it to make its final steady temperature θ2 to be about 5 to 60C bleow θR .
