Chapter 19: Q. 11 (page 543)

500 J of work are done on a system in a process that decreases the system鈥檚 thermal energy by 200 J. How much heat energy is transferred to or from the system?

Short Answer

Expert verified

The value of heat is -700J

Step by step solution

01

Definition of first law of thermodynamics

First law of thermodynamics define the energy does not create or destroy in the universe.

02

Finding the value of heat energy 

As Ethi=W+Q

The work done is positive as energy is transferred from environment to gas.

Ethi=-200JW=+500J

Now applying all values

The value of heat is Ethi=-200JW=+500JQ=Ethi=-W=-200J-500J=-700J
