Question

In a closed insulated container a liquid is stirred with a paddle to increase the temperature which of the following is true : -

Answer 1

Answer:

The First Law of Thermodynamics gives :

- - - ...

Q = Delta E + W sub B

Since compartment is protected - > Q = 0.0

The stirrer works on the System ( the fluid ) - > W sub < 0.0 < -

Accordingly : Delta E = - ( W sub B ) <-

Thermodynamic Work might be finished by the System on the Surroundings when the

Framework extends.

Thermodynamic Work might be done on the System when the System

is compacted or when the System is upset or mixed.
