Answer: An expansion valve.
Explanation:
The expansion valve is a copper tubing that contains a small orifice. The orifice restricts the flow of the refrigerant and makes it undergo a severe drop in pressure and temperature when it exits the orifice.
The temperature drop provides the cooling required in the cooling coils of the refrigerator.
Answer:
tthe body of what it is supplied in its temperature rises
Answer:
40L
Explanation:
Data obtained from the question include:
V1 (initial volume) = 60L
P1 (initial pressure) = 40mmHg
V2 (final volume) =?
P2 (final pressure) = 60mmHg
Using P1V1 = P2V2, the final volume can be obtain as illustrated below:
P1V1 = P2V2
40 x 60 = 60 x V2
Divide both side by 60
V2 = (40 x 60)/60
V2 = 40L
Therefore, the final volume is 40L
All forces on the bullets cancel so that the net force on a bullet is zero, which means the bullet has zero acceleration and is in a state known as constant velocity. The bullet is moving at a constant value of velocity. Acceleration is the rate of velocity so having zero acceleration would mean that there is no change in velocity per unit of time.<span />
