2) a&b

km, mind a numerical value for 3. 2. An object with surface area A is placed in an oven which is maintaining temperature Towen. The object has a heat m, and an initial temperature To. In this problem, ignore any heat transfer by conduction or convection, and assume the oven doesn't lose any heat to the outside environment. Also assume that the time for the objects to reach a steady state is much faster than any other time scales in this problem (so we will always assume our system is in a "steady state) At time t, the object has temperature T().

Explanation / Answer

(a)

The net rate of heat gain by an object given as :

Q = h A (T - T0)

h = heat transfer coefficient, W/m2K

A = surface area of an object, m2

T = object temperature, K

T0 = initial temperature object, K

Q = heat transferred, J/s

then, we get

The equation of solve....

(q / t) = h A (T - T0)

It is the solutions of heat given object...
