A freezer has a coefficient of performance 2.40, the freezer is to convert 1.80kg of water at 25°c to 1.8 of ice -5°c in one hour. What amount of heat must be removed from the water at 25°c to convert it to ice at -5°c?. How much electrical energy is consumed by the freezer during this hour ?. How much wasted heat is delivered to the room in which the freezer sits?

Using data from seismic waves, geologists have learned that earth’s interior is made up of several

Explain that newton first law, second law and third law of motion?

How do temperature and salinity affect deepwater currents? as temperatures and salinity levels of water increase, the water rises to the surface where it creates currents as it moves to colder regions. they create changes in wind direction, moving denser water in the same direction as the wind and causing the deepwater circulation patterns found in the ocean. they equalize the forces on undersea currents caused by the coriolis effect as they replace more dense water with less dense water. they create density differences that cause dense deepwater currents to flow toward the equator where they displace less dense, warmer water above them.
