AI Thread Summary
To calculate the energy required to evaporate Earth's oceans, the method involves using the equations E=Q=mL and Q=mc(t1-t2). The average surface temperature of ocean waters is approximately 17 degrees Celsius, which must be considered when calculating the energy needed to raise the temperature to boiling before evaporation. The discussion emphasizes understanding the method rather than focusing on specific calculations. Resources are provided for accurate temperature data. This approach highlights the importance of both temperature and latent heat in the evaporation process.

Homework Statement


Philosophizing in physics lessons ... How much energy is needed to evaporate all the oceans on Earth?


Homework Equations


So, I think: E=Q=mL
And variables i found...

I don't care specific calculation, I interested in method... It is good?

Sorry for my bad English and thanks!

Don't forget you need to raise the temperature to boiling as well. What's the average temperature of the oceans?
 
Ouu, yes...
So, first: Q=mc(t_1-t_2) an then Q=mL?
The average temperature of the ocean surface waters is about 17 degrees Celsius (62.6 degrees Fahrenheit). BY: http://www.windows2universe.org/earth/Water/temp.html
 

Thread 'Struggling to understand the concept of this question (ice cube in water optics question)'

TL;DR Summary: I came across this question from a Sri Lankan A-level textbook. Question - An ice cube with a length of 10 cm is immersed in water at 0 °C. An observer observes the ice cube from the water, and it seems to be 7.75 cm long. If the refractive index of water is 4/3, find the height of the ice cube immersed in the water. I could not understand how the apparent height of the ice cube in the water depends on the height of the ice cube immersed in the water. Does anyone have an...

Thread 'Rolling without slipping on a curved surface'

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 .
