10-2.Transmission of Heat
easy
न्यूटन के शीतलन नियम का पूर्ण पालन होता है जबकि वस्तु एवं वातावरण के बीच तापान्तर है
A
${10^o}C$ से कम
B
${10^o}C$ से अधिक
C
${100^o}C$ से कम
D
${100^o}C$ से अधिक
Solution
(a) When temperature difference between the body and the surroundings is small, then loss of heat energy from the body is mainly due to the process of convection. In such a case, the rate of cooling of the body is governed by Newton's law of cooling.
