4. A typical house loses 10% of its heat through the windows. Its rate of heat loss (Q) depends on surface area of the window (S), the difference of the temperature (T) and the window resistance value R (in units of kgK.s3 ). How would the rate of loss change if the difference of the temperature is tripled? a) It would be doubled b) It would be half c) It would increase by the factor of 3 d) It would decrease by the factor of 3 e) It would remain constant
