Correct answer to the question 2 The figure shows the initial temperature of hot water in a beaker. The temperature of Beaker A would be 50°C and the temperature of Beaker … The table below shows the initial temperature of the four metals - 12469745 The temperature of Beaker B is 40°C. If we know the initial concentration of the thiosulfate ion (S 2 O 3 2-), that is the same for each experiment, and remember that it is all used up when the color of the solution changes, then we know that half the amount of I 2 was also consumed in Reaction 2. If energy is transferred as heat from a closed metal container to the air surrounding it, what is true of the initial temperatures of each? Then, calculate how much the temperature in each beaker changed during the interval. Express your answer with the appropriate units. The heat capacity of the beaker is equal to that of 20 g of water. The beaker is heated, ... one black and one white, are at the same initial temperature. after she mixes 105.1 g of water at 68°c with 105.1 g of water, already in the calorimeter, at 19.7°c, the final temperature of the water is 35.0°c.

Put both beakers on the gauze mat of each tripod. The beaker is heated reversibly so that the temperature of the beaker and water rise gradually to 57 ... A Carnot engine working between two heat baths of temperatures 600 K and 273 K completes each cycle in 5 sec. If this experiment were to be reproduced, one heat lamp should be used instead of two, and smaller thermometers would be more sufficient in the accuracy of the air temperature within the beaker. So that's 1100 times ten to the minus six, times 500 milliliters, times 22 degrees Celsius minus five degrees Celsius, giving 9.35 milliliters.
