(a) The partial pressure of O2 will decrease (b) The total pressure of the gases in the container will increase (c) The partial pressure of CO2 and O2 remain constant The answer given is (b) & (c),why?how to count?Please show the calculations. 2.) When a few crystals of ice are added to supercooled water at -5 degree Celcius,which of the following would happen? (a) More ice is precipitated (b) The vapour pressure increases (c) The temperature of the water increases The answer given is (a),(b)&(c),why?Please provide me some explanation.
