Thermodynamics

A small house has appliances that need 300 w power and a heater of er 1000 W. heat loss from the house is 600 W. Starting at 7o F. sketch the temperature variation (trend) in the house with time when (i) Only the appliances are turned ON (no heater) (ii) ON appliances) (iii) The appliances and heater are ON Assume each of the cases begins at t -0, there is no thermostat, and very briefly justify your answers. Hint: What is dT/dt proportional to? The solution is simply a straight line starting at with a certain slope. temperature 70F t (time)

Explanation / Answer

This is a physics question.

Still, What all I can help is

dT/dt = rate of change of temperature with time is energy

So, might be consider only power ( of the appliances) - 600W as heat loss and plot against the time frame.
