Assume that there are strong gusty winds and the extemal temperature is -7.0°C Express your answor to two significant fig and include the appropriate units EE) Q/t Value Units Submit My Answers Give Up Prov do Foodback ContinueExplanation / Answer
A) Use H = kA*(TH-TC)/L k for glass = 0.80 W/m*K So H = 0.8*(2.0*1.5)*(15--7)/.0028 = 18857.143 W
A) Q = ms*delT
Q = 37*4186*(89-24)
Q = 10067330 J = 1*10^7 J
