A well lagged wire of length L and cross-sectional area A has its ends maintained at temperatures T, and T2. The thermal conductivity of the wire is given by K = B + CT, where T is the temperature and B and C are constants. What is the rate of flow of heat along the wire?

A mass m of a metal with heat capacity CM at initial temperature T is added to the volume V of a liquid with density p and heat capacity c₁ at initial temperature T₁. What is the final temperature of the system?

An object has mass m, surface area A, temperature T, N molecules, and specific heat capacity c. The total thermal energy stored in the object is: Group of answer choices proportional to T^4 proportional to AT proportional to m proportional to cT proportional to NT

Thermography is a technique for measuring radiant heat and detecting variations in surface temperatures that may be medically, environmentally, or militarily meaningful.(a) What is the percent increase in the rate of heat transfer by radiation from a given area at a temperature of 34.0C compared with that at 33.0C, such as on a person’s skin? (b) What is the percent increase in the rate of heat transfer by radiation from a given area at a temperature of 34.0C compared with that at 20.0C, such as for warm and cool automobile hoods?
