1. Given e_sw = 57mb and r = 0.5, find T_LCL.

2. An air mass has a temperature of 68ºF at 970hPa with a mixing ratio of 5 g kg^-1.

Without any condensation or mixing the air mass now has a temperature of 50ºF and a pressure of 750hPa. Find the initial and final values of (a) r, (b) Tdew and (c) vapour pressure.

3. Place the following temperatures in order from least to greatest:

T, T_virt, T_dew, T_w, T_ei, T_LCL

4. Using the same temperatures as problem 3, explain using thermodynamically sound principles what each temperature represents.
