A house is maintained at 1 atm and 24 oC, and warm air inside a house is forced to leave the house at a rate of 150 m3 /h as a result of outdoor air at 5 oC infiltrating into the house through the cracks. Determine the rate of net energy loss of the house due to mass transfer.

What happens to light waves from a star as the star moves away from earth?

Acalorimeter uses the principle that thermal energy flows from hotter material to colder material until both reach the same

Cells in the nervous system have a potential difference of 70 mv across the cell membrane separating the interior of the cell from the extracellular fluid. this potential difference is maintained by ion pumps that move charged ions across the membrane. is this an emf? select the correct answer and explanation. 1)no. the ion pumps cannot separate charges; thus, they cannot create a potential difference. 2)yes. the ion pumps cannot separate charges, but they still can create a potential difference. 3)yes. the ion pumps can actively separate charge; thus, they can create a potential difference. 4)no. the ion pumps can separate charges, but they cannot create a potential difference.
