1. How much energy is lost by 20 kg copper if it is cooled from 50°C to 30°C?
I was hoping that you could check to make sure I’m using the correct units. For some reason I am having a hard time understanding when to use 4186 for specific heat of water or 4.186. For the latent heat of fusion, I have it in kg•cal degrees C. In my book it has it in J/kg. Since the book says it is 3.33 X 10^5, how do I get my answer to show in those terms? Thank you!
possible to have water vapor at 210°C?
A. 1.00 kg of liquid nitrogen (N2) at its boiling/vaporization point (-195.81 °C) is poured into a large reservoir of liquid water at it fusion/melting point (0.00 °C). How many kilograms of ice (at 0.00 °C) will the evaporation of the liquid nitrogen create (mice = ?)?
