State Change due to Pressure

pH of 0.1M solution HCl is changed by 0.3 unit due dilution, calculate change in osmotic pressure if temperature of solution is 300K. (R = 1//12" " "litre atm"//K//"mole")

Pure gas'A' was taken in a closed container at an initial pressure of 5 atm. The pressure in the container changed due to reactions. A(g)hArrB(g)+2C(g) C(g)hArrB(g)+D(g) If the total pressure due to mixture of gas A,B,C and D was found to be 10 atm, in which pressure due to C was 3 atm. Find K_(p) for first equilibria.

The process of transformation of a substance in a gaseous state into a liquid state due to change in pressure or temperature of the substance is called_______

Two moles of an ideal monoatomic gas are expanded according to the equation pT=constant form its initial state (p_0, V_0) to the final state due to which its pressure becomes half of the initial pressure. The change in internal energy is

Systolic pressure is higher than diastolic pressure due to :-
