(T - T1 ) / (t2 - t1) = constant
perhaps T1 = temperature at time t = t1 sec
T = temperature t time t = t2 sec
The ratio is constant means the rate of change of temperature is a constant. The temperature of a body is rising at a uniform rate in time.
This means that the body is getting cooled or getting heated at a uniform rate.
This could probably mean that the body is being supplied a constant amount of heat energy in time. This means energy/time = power is a constant.
