Refrigerators remain among the greatest consumers of electrical energy in most homes, although mandated efficiency standards have decreased their energy consumption by some $80 \%$ in the past four decades. In the course of a day, one kitchen refrigerator removes $30 \mathrm{MJ}$ of energy from its contents, in the process consuming $10 \mathrm{MJ}$ of electrical energy. The electricity comes from a $40 \%$ efficient coal-fired power plant. The electrical energy a. is used to run the light bulb inside the refrigerator. b. wouldn't be necessary if the refrigerator had enough insulation. c. retains its high-quality status after the refrigerator has used it. d. ends up as waste heat rejected to the kitchen environment.

In this party with a problem That or did you have to? Righties? Well, power is dubbed the dark. It was it up or and three to kill a lot. Dying in ours. He's syrup or into five times 24 hours a day. Times 30. And this comes out to be our per year cost or price or unit price. Unit price. It was 0.9 So you have crossed. It was W dark times, timing hours a year. Times the unit price. Ah WTI dimes Time in our party year times unit price And this will come out to be dollar 5.1 aid So the correct answer is option B.

So here in this problem, we have to calculate the amount of feet removed by the refrigerator from the refrigerator. Space in hell on the given day days. No, the power consumed by the refrigerator trolled. The U is 6 80 kilowatt hour on the coefficient of performance off. The three were given us a 1.4 and there are five options given in the problem. Andre. After the lead, which option is correct? So a fuss Terfel will be calculating the value of fuel dot and killed or a denotes the amount of heat were removed by the refrigerator. So from the definition off Seop, begin right that you will dot It will be equals two c o p. Offer refrigerator times the power input. So you're literally here. Seop is 1.4 times the power input is six particular what hours And if you convert doing it, we know that one kilowatt hour Is it cool in security? 600 Killer Jewell. From here we get the value US 3000 427.2 times 10 to the bo tree Cool a jewel So this amount of heat is removed by the refrigerator in here so we can write cool dot is it cools to 3427.2 Mega jewell for a year. But this much amount of heat is being removed from the refrigerator, but from the left of your to space. So again say, in the end of that option, B is correct because it's matching with done. So I hope you got the problem. Thank you.

So the given function. Are they see is there well done some flight? The Cuban not Is taking temperature from equals 273. And Committing with Q. two years stone 93 in kelvin degree, Caliban degree. So first of all for SEOP for refugees. And we know that formula the yellow bone th minus tear. So this is the formula of C. O. P. The lower the higher ministerial heard this valuable way two 73 upon 293 273 which will be 2731. Does that meanwhile on the right hand side we can stop. You can also be written as You 2 1 W. Yes he rejected upon bogdan. So he just divide by time on both up and down side. So it becomes cute dot www dot Yeah Means he rejected per second by well done per second equals two 273 x 20. Yeah your duty is given. Yes 2.2 kilo june per second. So w what will be 2.2 from here? This formula in 20 By 273 and the sense it is intelligible, we just can't work in jewels. So final answer calculating this, we will have. The final answer is 161 point 17 jewel, approximate jewel per second. The jewel per second unit is what? So we can also see it as 16, What?

How long now we are going to discuss conclusion. The pressure in A. Represented A. Is located at the top section. So that The three Year in the representatives located the top section. So that means that you suddenly asking us why the creature is representative. It's located at the top section. And options are given as four options are given us in the entire chamber of the review. Could quickly due to the election option B. The motor is not heated option see that it again from the environment. The high often the the height heat again from the environment is below. So right answer of the institution. Each option t right answer of the execution is option mm Cooperating between two times. Sorry that entire chamber of the refrigerator is cooled quickly. You do conviction the and uh chamber all of them every year. Uh huh. Yeah, it's good. He believes quickly. Do you do grandson conviction in the process, conviction in the process process uh process of uh medium circulation in the air circulation. You do the identity difference So there called them in that in that the cordillera region. The cold air is identity in the cold air identity asia higher. So the cold air is downs and uh who are mary density is low. So warm air is comes up with uh and contact with three years. So conduction, convection heater connection with a proceeding in which the entire chamber of the directors. It's called to be a conviction. That is the right answer. Up that conclusion. Thank you
