Question

A spherical object which behaves as a black body is raised to the temperature T and placed in an environment initially at o c While the object cools from T to the temperature T in an interval of time t t the environment rises to the temperature 1 C during the same time The average rate of cooling of the object dT and the average rate net to dt dT are respectively given by a and 0 B while the dt heat loss Q of the object during the time interval 0 same quantities during the interval 4 t are a and 0 B Read the following statement about this system State which of the above statements are true by correct choice from below 3T dT 4 dt E a B Ba a a B B The newton s law of cooling will be more accurate near then near 1 0 or 1 T The rate of cooling decreases with time at first reaches a minimum and then increases with time
