In the laboratory method for measuring the latent heat of steam, the steam is passed through the device shown above. The function of the device is (a) to prevent condensed steam reaching the calorimeter (b) to reduce the pressure of the steam (c) to ensure that the pressure of the steam is equal to the atmospheric pressure (d) to control the rate of flow of steam |

Answer» Correct Answer is: (a) to prevent condensed steam reaching the calorimeter The arrangement is commonly called a "steam trap". The steam which condenses into water in the rubber pipe from the boiler remains inside this device and does not reach the calorimeter. This removes a major source of error in the experiment. |
