AI Thread Summary
Leaving a refrigerator door open in an enclosed room will not cool the room over time; instead, it will increase the room's temperature. This is due to the energy consumption of the refrigerator, which generates heat as it operates. The coefficient of performance (COP) indicates that for every unit of energy used, more heat is expelled into the room than the cooling effect provided. The discussion also touches on the power output and energy input of the refrigerator, emphasizing that the energy input contributes to the overall heat in the room. Ultimately, the refrigerator's operation leads to a net increase in room temperature rather than cooling.

The Attempt at a Solution


I am thinking of the warm air/cool aire situation in my way of answering this problem. Any advice as to what the correct answer might be?

Thanks.

I think yes. let the refrigerator open until one year.
 
Hint: Does the refrigerator require energy input? What happens to that energy?
 
I have a question, the COP of a refrigerator is 8, the Power output is 1.6kW. what is the input?
 
Thread 'Collision of a bullet on a rod-string system: query'
In this question, I have a question. I am NOT trying to solve it, but it is just a conceptual question. Consider the point on the rod, which connects the string and the rod. My question: just before and after the collision, is ANGULAR momentum CONSERVED about this point? Lets call the point which connects the string and rod as P. Why am I asking this? : it is clear from the scenario that the point of concern, which connects the string and the rod, moves in a circular path due to the string...
