For N_2O_4(g) to 2NO_2(g) , pressure is found to be increased from 700 mm to 800 mm in 10 min. Then (-Delta [P])/(Delta t) with respect to N_2O_4 is

A gaseous phase reaction A_2 to B +0.5C shows an increase in pressure from 100 mm to 120 mm in 5 min. Now, - (Delta [A_2])/(Delta t) should be

Most substances contract on freezing. However, water does not belong to this category. We know that water expands on freezing. Further, coefficient of volume expansion of water in the temperature range from 0^(0)C to 4^(0)C is negative and above 4^(0)C it is positive. This behaviour of water shapes the freezing of lakes as the atmospheric temperature goes down and it has an extremely important effect on plant and animal life in lakes. Under fixed atmospheric conditions, if it takes 2 hr. to form a 1 cm thick layer of ice in a lake, time taken for the thickness of ice layer to grow further by 1 cm will be

In a gaseous phase reaction A_(2)(g)toB(t)+1(1//2)C(g) , the increase in pressure from 100 mm to 120 mm is noticed in 5 minute.The rate of disappearance of A_(2) in mm "min"^(-1) is

An air bubble comes from the bottom to the surface of a lake of depth 2.5 m. The surface temperature of the lake is 40^(@)C . The diameter of the bubble at the bottom and at the surface are 3.6 mm and 4 mm respectively. Find the temperature of the lake at the bottom.

Two tubes of same length and diameters 4mm and 8mm are joined together to form a U-shaped tube open at both the ends. If the U-tube contains water, then the difference between the levels of water in the two lims of the tube is (Surface tension of water at the temperature of experiment is 7.3 xx 10^(-2) Nm^(-1) , angle of contact = 0^(@) , density of water = 1.0 xx 10^(3) kg m^(-3) and acceleration due to gravity = 10 ms^(-2) )
