Homework Help Overview

The discussion revolves around the energy required to evaporate all the oceans on Earth, exploring the physics concepts involved in phase changes and temperature changes of water.

Discussion Character

  • Exploratory, Conceptual clarification, Mathematical reasoning

Approaches and Questions Raised

  • Participants discuss the energy equation E=Q=mL and consider the need to account for temperature changes before evaporation. Questions arise about the average temperature of the oceans and its relevance to the calculations.

Discussion Status

Some participants have provided insights into the necessary calculations, including the need to raise the temperature to boiling before evaporation. There is an ongoing exploration of the average ocean temperature and its implications for the problem.

Contextual Notes

Participants note the distinction between surface temperature and deeper ocean temperatures, indicating a potential area of confusion or further inquiry.

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!
