THERMODYNAMICS

Question 1

What is Thermodynamics?

Answer 1

It is the science of the relationship between heat, work done, temperature and energy

Question 2

First Law of Thermodynamics

Answer 2

The law of conservation of energy states (adapted for thermodynamics) that the total energy of an isolated system is constant; energy can be transformed from one form to another, but can be neither created nor destroyed.

Question 3

Equation denoting relationship between change in energy and work done in a thermodynamic closed system.

Answer 3

Delta U = Q+W
where:
Delta U = change in internal energy of a closed system. 
Q = quantity of energy supplied (heat)
W = work done.
