What are the laws of Thermal Dynamics?

Answer 1

1. You do not talk about thermodynamics

2. You DO NOT TALK about thermodynamics

3. One fire at a time

4. Fires will go on as long as they have to

5. If this is your first night, you have to fire

Answer 2

1st law: Enery can neither be created nor destroyed,but it can be transformed from one place to other.

2nd law: (i) No heat engine is more efficient than tha theoretical carnot engine.

(ii) In a closed system entropy can never decrease.

(iii)There are irreversible processes.

3rd law: If the kinetic energy of all the molecules is removed then a state called absolute zero will occur.

Answer 3

There are four laws of Thermodynamics

Zeroth Law - If any two systems are in equilibrium (balance) with each other and either one is balance with a third system then it can be assumed that they are all equal; that is in equilibrium.


First Law - Energy can not be created or destroyed, it can only change forms. The rate of change in energy in one system must equal the rate of change in energy in an opposing system. If system A decreases by one degree then System B will increase by one degree.


Second Law - Heat or Energy can only flow from a higher energy system to a lower energy system but not the other way around.


Third Law - As a system approaches absolute zero all processes cease and activity continues at a minimum rate. This basically means that you can not reduce anything below absolute zero because that is the activity at which there is no energy present.

Answer 4

It is commonly known as priniciple of the conservation of energy

energy can be neither created nor destroyed but it may be converted from one form to another

The total energy of an isolated system remains constant though it may change from one form to another

e=q+w

q= amount of heat suppplied to the system

w= work done by the system

Answer 5

The laws of thermodynamics are fundamental principles that govern energy transfer in physical systems. The four laws are: 1) The Zeroth Law states that if two systems are in thermal equilibrium with a third system, they are in thermal equilibrium with each other. 2) The First Law, also known as the Law of Energy Conservation, states that energy cannot be created or destroyed, only transferred or converted. 3) The Second Law states that in any energy transfer or transformation, the total entropy of a closed system will never decrease. 4) The Third Law states that as temperature approaches absolute zero, the entropy of a system approaches a minimum value.

Answer 6

1. energy is conserved

2. Heat flows from T h to T l spontaneously.
