Say that you are in a large room at temperature TC = 300 K. Someone gives you a pot of hot soup at a temperature of TH = 340 K.

You set the bowl up so that as it cools to room temperature the heat first flows through a Carnot Engine. The soup has Cv= (33 J/K). Assume that the volume of the soup does not change.
1. What fraction of the total heat QH that is lost by the soup can be turned into useable work by the engine?

Answer:

Explanation:

Heat energy given out by the soup

= C_v  x ( t₂ - t₁ )

= 33 x ( 340 - 300)

= 1320 J

This heat is given to Carnot engine . Efficiency of engine

= (340 - 300 ) / 340

= 40 / 340

2 / 17

This fraction of total heat given is converted into useable work by the engine.

I'm doing a presentation over real-world applications of physics and the group I am in wants to do "the physics of video games"
artcher [175]
Most modern games have a sense of real-world physics, but not exactly perfect. In a video game, the realistic movement or action greatly depends on the precision of coding. In real life, movement isn't done or programmed by a strand of code.

Your presentation sounds interesting, being a gamer myself, I would look forward to it. But the choice lies in your hands. If you do reconsider, be sure you have a backup plan. Good luck to you.
