Thermodynamics expansion problem

AI Thread Summary
The problem involves calculating the depth of a swimming pool that overflows when water warms from 24 °C to 34 °C. The volume expansion coefficient for water is given as 2.07 x 10^-4 °C−1. The initial attempt incorrectly equated the change in depth (1.2 cm) with the change in volume. Clarification revealed that the change in volume should be calculated using the volume expansion formula, and the correct approach does not require taking the cube root. The user successfully found the correct answer after receiving guidance.

Homework Statement


On a hot summer day, a cubical swimming pool is filled to within 1.2 cm of the top with water at 24 °C. When the water warms to 34 °C, the pool overflows. What is the depth of the pool? (The volume expansion coefficient for water is 2.07 10-4 °C−1.)


Homework Equations


ΔV = βV0ΔT


The Attempt at a Solution


I set ΔV equal to 1.2, plugged the numbers in, got 193.24 cm3 for the volume, and took the cube root of the result for the depth. That didn't work. What am I supposed to do?

Hi xnitexlitex! :smile:

ΔV is not equal to 1.2.
1.2 cm is the change in depth, not the change in volume.

How did you plug your numbers in and get your volume?
Because I see no reason why you would need to take a cube root...
 
Thank you. I just got the answer now.
 
Kindly see the attached pdf. My attempt to solve it, is in it. I'm wondering if my solution is right. My idea is this: At any point of time, the ball may be assumed to be at an incline which is at an angle of θ(kindly see both the pics in the pdf file). The value of θ will continuously change and so will the value of friction. I'm not able to figure out, why my solution is wrong, if it is wrong .

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 'Trying to understand the logic behind adding vectors with an angle between them'
My initial calculation was to subtract V1 from V2 to show that from the perspective of the second aircraft the first one is -300km/h. So i checked with ChatGPT and it said I cant just subtract them because I have an angle between them. So I dont understand the reasoning of it. Like why should a velocity be dependent on an angle? I was thinking about how it would look like if the planes where parallel to each other, and then how it look like if one is turning away and I dont see it. Since...
