Suppose 50.0 dm3 of dry air at 25c was slowly bubbled through a thermally insulated beaker containing 250g of water initially at 25c. calculate the final temperature of the liquid. the vapour pressure of water is approximately constant at 3.17 kpa throughout, and the heat capacity of the liquid is 75.5 j k-1 mol-1. assume that the exit gas remains at 25c and that water vapour is a perfect gas. the standard enthalpy of vapourization of water at 25c is 44.0 kj mol-1. (hint: start by calculating the amount in moles of h2o in the 50.0 dm3 of air after it has bubbled into the liquid)
