Water with a small salt content (5kg per 1000 liters) is flowing into a very salty lake at the rate of 4 x 105 li/hr. The salty water is flowing out at the rate of 105 li/hr. If at some time (t=0) the volume of the lake is 109 liters, and its salt content is 107 kg, find the salt content at time, t. Assume that the salt is mixed uniformly with the water in the lake at all times.

Boiling of water in an open container is a constant pressure process. On earth water boils at 100 deg C (atmospheric pressure is 101.3 kPa). If we were to boil 2 kg of water on the surface of Mars, how much energy (Q) do we need to supply? The ΔU for this process is 4750 kJ. Specific volumes of water vapor and liquid are 206.00 and 0.00100 m3/kg, respectively.
