Drug has heat of melting 25 K jule/mole. Solubility of drug in water is 0.00082 M at 25 C and 0.00144M at 35 C. Find mole fractions x1 and x2 at each temperature.

A man walks 40 m due north and 50 m due west. Find the distance from the starting point?

I know that way. But what is the difference in mole fraction of drugs and solvent (water) at different temp?

thermo dynamic variables which are not path depends are called independent variables. for example- pressure, temperature, volume, number of moles are independent variables. Only work and energy is dependent variables. they are path dependent.

flow rate in narrow tube is 16times less than in wide tube. speed in narrow tube will be 4time smaller than wide tube
