4. What is the rate of heat flow through a glass window that is 4m by 5m and 1.25cm thick if the outside temperature is 28 °C and the inside temperature
is 35 °C. Thermal conductivity of glass is k = 0.84 J s-1m-1k-1

This is important 1. what happens to the speed of molecules in water vapor when it condenses to form a liquid? (2 points) the molecules slow down. the molecules speed up. the molecules slow down and then speed up. the molecules speed up and then slow down. 2. how might human activities change to compensate for a decrease in water supplies? (2 points) humans might build a factory. humans might build drainage systems. humans might extract more water from the ground. human behavior does not change because of the water cycle. i'll be grateful if anyone can answer these 2 questions !
