A glass windowpane in a home is 0.62 centimeter thick and has dimensions of 1.12 m × 2.10 m. On a certain day, the indoor temperature is 26°C and the outdoor temperature is 0°C. (Suppose the thermal conductivity of the glass is 0.8 J/s•m•°C.)
(a) Find the rate at which energy is transferred by heat through the glass?
_________W
(b) Determine how much energy is lost through the window in one day, assuming the temperatures inside and outside remain constant?
_________J
