Temperature of a certain place is `12^@C`. If the temperature reduces uniformly in every hour and reaches to -` 40^@C` after 8 hour. Let's find the rate of reduction of temperature hour.

Surface of a lake is at 2^(@)C . Find the temperature of the bottom of the lake

Rate of BMR increases - for the increase of 1^@C body temperature is -

The rate of a chemical reaction doubles for every 10^(@)C rise of temperature . If temperature is raised by 50^(@)C rate to the reaction increases by about-

A body at a temperature of 50^(@) F is placed outdoors where the temperature is 100^(@) F. If the rate of change of the temperature of a body is proportional to the temperature differenece between the body and its surrounding medium. If after 5 min the temperature of the body is 60^(@) F, find (a) how long will take the body to reach a temperature of 75^(@) F and (b) the temperature of the body after 20 min.

At 0 degree C soil temperature the rate of water absorption

Two first order reactions proceed at 25^@C , at the same rate. The temperature coefficient of the rate of first reaction is 2 and that of the second reaction is 3.find the ratio of rates of these reactions at 75^@C

In another mine, the lift goes down 4 m in every one min. what will be the position of the lift after an hour, Let's find.

Volume of a room is 15 m times 12 m times 8m . The room was at 22^@C in the morning.What is the percentage of initial volume of air of the room that is expelled when the room temperature reaches 30^@C at noon? The pressure remains constant during the increase in temperature ,atmospheric pressure remains constant.
