Read the following paragraph and answer the questions. If heat is exchanged between a hot and cold object, the temperature of the cold object goes on increasing due to gain of energy and the temperature of the hot object goes on decreasing due to loss of energy. The change in temperature continues till the temperatures of both the objects attain the same value. In this process, the cold object gains heat energy and the hot object loses heat energy. If the system of both the objects is isolated from the environment by keeping it inside a heat resistant box (meaning that the energy exchange takes place between the two objects only), then no energy can flow from inside the box or come into the box. Which principle do we learn about from this process?

If the system were lossing heat according to Newton's cooling law the temperature of the mixture would change with time according to (while heater was on) .

Assertion: According to Newton's law of cooling, the rate of loss of heat, -dQ//dt of the body is directly proportional to the difference of temperature. Reason :This law holds for all type of temperature differences.

Consider the following statements with respect of zero order reaction. (i) The rate of the reaction is independent of reactant concentration (ii) The rate of the reaction is independent of temperature (iii) The rate constant of the reaction is independent of temperature (iv) The rate constant of the reaction is independent of reactant concentration Choose the correct statement (s)

A metal bal of mass 1 kg is heated by means of a 20 W heater in a room at 20^(@)C . The temperature of the ball becomes steady at 50^(@)C . Assume newton's law of cooling to hold good in the given situation. The temperature of the bal rises uniformly from 20^(@)C to 30^(@)C in 5 minutes. select the correct alternatives (1) The rate of heat loss by ball to surrounding is 20 W, when it is at 50^(@) (2) Ther ate of heat loss by ball to surrounding is (20)/(3)W , when it is at 30^(@)C (3) The rate of heat loss by ball to surrounding 20 W, when it is at 30^(@)C (4). The specific heat capacity of the gas is 500 J/kg K.
