Mixing of acetone and chloroform occurs with reduction in volume and is exothermic process. What change will occurs in vapour pressure ? Explain your answer.

It is predicted by the meteorologists that global warming will result in the flooding of oceans due to the melting of ice caps on the earth . During the melting process what changes will occur to its internal energy.

Power stations are centres that generate and distribute large quantities of electricity. Power transmission is the process of sending electricity to distant places through wires from the power stations What change will occur in power when intensity of current is reduced in the circuit ?

What change occurs for power of a lens when its focal length increases ?

A mixture of chloroform and acetone does not obey raoult 's law under all conditions:Represent this deviation using a vapour pressure composition curve.

A,B,C and D are four gases. 2 mole A react with 3 mole B to form 2 mole C and mole D. in this reversible reaction, forward reaction is exothermic. Write the chemical equation for the reaction and answer thefollowing questions. a) If the system is at eqilibrium, what will be the effect of increase in pressure on the system? b) What is the effect of change in temperature?

Can equilibrium be achieved between water and its vapours in an open vessel? Explain your answer stating what happens eventually.
