Look at the figures and suggesat in which of the vessels a,b,c and d the rate of evaporation will be the highest. Explain.

Which of the following exhibits the highest rate of respiration ?

Look at the adjacent figure. Find the number of unit cubes in cube A and cube B and find the ratio.

A child running a temperature of 101 ^(@) F is given an antipyrin (1.e. a medicine that lowers fever) which causes an increase in the rate of evaporation of sweat from his body. If the fever is brought down to 98^(@) F in 20 minutes, what is the average rate of extra evaporation caused by the drug. Assume the evaporation mechanism to be the only way by which heat is lost. The mass of the child is 30 kg The specific heat of human body is approximately the same as that of water, and latent heat of evaporation of water at that temperature is about 580 " cal g"^(-1) .

Which explains the effect of a catalyst on the rate of a reversible reaction?

Which animal has the highest heart beat rate ?

A conical vessel of height 10 ft and semivertical angle 30^@ is full of water. It empties in such a way that the height of water in the vessel is decreasing at a constant rate of 1 inch per minute. The rate of which the volume of water in the vessel is decreasing when its height is 6 ft is
