A glass windowpane in a home is 0.62 cm thick and has dimensions of 1.1 m multiplied by 1.6 m. On a certain day, the indoor temperature is 20°C and the outdoor temperature is 0°C.
a) What is the rate at which energy is transferred by heat during the glass?
b) How much energy is lost during the window in one day, assuming the temperatures inside and outside remain constant?
