Write the difference between heat and temperature .

A metal ball of mass 1.0 kg is kept in a room at 15^(@)C . It is heated using a heater. The heater supplies heat to the ball at a constant rate of 24 W. The temperature of the ball rises as shown in the graph. Assume that the rate of heat loss from the surface of the ball to the surrounding is proportional to the temperature difference between the ball and the surrounding. Calculate the rate of heat loss from the ball when it was at temperature of 20^(@)C .

A hot body is suspended inside a room that is maintained at a constant temperature. The temperature difference between the body and the surrounding becomes half in a time interval t_(0) . In how much time the temperature difference between the body and the surrounding will becomes (1)/(4) the original value?

A body at a temperature of 50^0F is placed outdoors where the temperature is 100^0F . If the rate of change of the temperature of a body is proportional to the temperature difference between the body and its surrounding medium. If after 5 min the temperature of the body is 60^0F , find (a) how long it will take the body to reach a temperature of 75 ^0 F and (b) the temperature of the body after 20 min.

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.
