In the apparatus used to determine the specific latent heat of vaporisation of steam, the steam trap is used to ensure that only dry steam gets into the calorimeter. The steam trap works by allowing the steam to pass through it, but trapping any condensed steam or water droplets that may be present in the steam. This is important because if any water droplets or condensed steam get into the calorimeter, they will add to the heat energy in the system and affect the accuracy of the measurement. By trapping any condensed steam, the steam trap ensures that only dry steam gets into the calorimeter, which allows for a more accurate measurement of the specific latent heat of vaporisation of steam. Therefore, the correct option is: ensures that only dry steam gets into the calorimeter.
