Discover smallest possible amount of heat expelled into room

Reference no: EM13680438

The Kwik-Freez Appliance Co wants you to design a food freezer that will keep the freezing compartment at -5.00C and will operate in a room at 20.0C. The freezer is to make 5.80kg of ice at 0C, starting with water at 20.0C.

1) Discover the least possible amount of electrical energy required to make this ice

2) Discover the smallest possible amount of heat expelled into the room.

Where the center of the sphere is located at the origin : A metal sphere of radius R = 30 cm carries a total charge Q = 2.0 µC. What is the magnitude of the electric field at a point 5 m away? The point is located on the positive x-axis, where the center of the sphere is located at the origin.

Positively charged particle in an elliptical orbit : A 6.9 C negative point charge has a positively charged particle in an elliptical orbit about it. If the mass of the positively charged particle is 1.0 micrograms and its distance from the point charge varies from 4.0mm to 16.0mm, what is the maximum ..

Why arenot d-branes-strings independent degrees of freedom : A condensate of open strings with both ends attached to the same D-brane can be equivalent to a displacement of the D-brane with no open string condensate. A solution to the D-brane Born-Infield action gives rise to a semi-infinite string extension w..

Fluid depends upon the fluid density : The speed of sound V in a fluid depends upon the fluid density? And its bulk modulus B as follows: v = ^n.B^m. Using dimensional analysis, find the values of constants N and m, respectively. The unit of density is kg/m3 and that of bulk modulus B is ..

Test charge from a point midway-either of the charges : A +50 µC charge is placed 34 cm from an identical +50 µC charge. How much work would be needed to move a +0.42 µC test charge from a point midway among them to a point 8.0 cm closer to either of the charges?

What normal force does person feel as elevator decelerates : You are riding in an elevator that is traveling down .It travels at vo=6m/s downward. Then, over two seconds, it slows to a stop. What normal force does the person feel as the elevator decelerates? (Mp=75kg) What is the acceleration of the elevator? ..

How high is the wall : Jared a small Cannon with a ball .He launches the ball at an angle of 70 degree, and vo=32m/s. It travels up and right toward the wall. It just clears the wall( at it max height). How high is the wall? How long (time) does it take for the ball to tra..

High density core surrounded with a lower density shell : Bowling balls can be made from a variety of substances and are needed to have a circumference of roughly 27.2 inches. The construction of the ball typically consists of a high density core surrounded with a lower density shell.
