AI Thread Summary
The discussion revolves around a calorimetry problem involving a nurse cooling a 2.40 L bottle of soft drink by adding ice and using an aluminum mug. The key equations used include heat transfer calculations for the ice, soft drink, and mug, with specific heat capacities and latent heat values provided. The user initially struggles with the calculations but ultimately concludes that the final temperature of the system is 15.1 degrees Celsius. The conversation highlights the importance of correctly applying the principles of heat transfer and ensuring all components are accounted for in the calculations. The final result indicates successful problem-solving despite initial confusion.

Homework Statement



A thirsty nurse cools a 2.40 L bottle of a soft drink (mostly water) by pouring it into a large aluminum mug of mass 0.250 kg and adding 0.123 kg of ice initially at -15.5 degree celsius . If the soft drink and mug are initially at 20.2 degree celsius, what is the final temperature of the system, assuming no heat losses?

Homework Equations



Q1+Q2+Q3+Q4+Q5=0
Q=Mc(change in T)
Q=ML
C ice= 2010 (given)
C water = 4190 (given)
C Al= 904
L = 3.34*10^5 (given)
M drink = Density *Volume = (1000)(.0024)=2.4

The Attempt at a Solution



Q1=M ice (C ice) (Temp) = .123(2010)(0--15.5) = 3832
Q2=M ice (L) = .123 (3.34*10^5) = 41082
Q3=M ice (C water) (Temp) = .123 (4190)(T-0) = 515.4 (T)
Q4=M drink (C water) (Temp) = 2.4 (4190) (T-20.2) = 10056 (T-20.2)
Q5=M Al (C Al) (Temp) = .25(904)(T-20.2) = 226 (T-20.2)

(3832)+(41082)+515.4 (T) + 10056 (T-20.2) + 226 (T-20.2) = 0

I keep getting the wrong answer. I think I am missing a Q or misinterpreting one of them

never mind I was right 15.1 is the final temp
 
Thread 'Voltmeter readings for this circuit with switches'
TL;DR Summary: I would like to know the voltmeter readings on the two resistors separately in the picture in the following cases , When one of the keys is closed When both of them are opened (Knowing that the battery has negligible internal resistance) My thoughts for the first case , one of them must be 12 volt while the other is 0 The second case we'll I think both voltmeter readings should be 12 volt since they are both parallel to the battery and they involve the key within what the...
Thread 'Correct statement about a reservoir with an outlet pipe'
The answer to this question is statements (ii) and (iv) are correct. (i) This is FALSE because the speed of water in the tap is greater than speed at the water surface (ii) I don't even understand this statement. What does the "seal" part have to do with water flowing out? Won't the water still flow out through the tap until the tank is empty whether the reservoir is sealed or not? (iii) In my opinion, this statement would be correct. Increasing the gravitational potential energy of the...
