Suppose 50.0 dm3 of dry air at 25c was slowly bubbled through a thermally insulated beaker containing 250g of water initially at 25c. 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 25c and that water vapour is a perfect gas. the standard enthalpy of vapourization of water at 25c 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)
