• 9 11.2.1 First law of thermodynamics – The first law of thermodynamics is based on the law of conservation of energy, which states that energy cannot be created or destroyed, but can be transferred from one form to another. As gas turbines are heat engines, converting heat into work, the first law requires that we cannot produce more work than the heat supplied.

## Which of the following statements of the first law of thermodynamics is correct?

Which of the following statements best describes the first law of thermodynamics? Energy cannot be created or destroyed.

### Which of the following is an example of the first law of thermodynamics?

Choose the correct option. Which of the following is an example of the first law of thermodynamics? – Physics | Shaalaa.com After falling down the hill, a ball’s kinetic energy plus heat energy equals the initial potential energy. Explanation: There are three laws of thermodynamics.

The expression obtained is, ΔU = Q – WHere, ΔU is the change in internal energy.Q is the heat added to the system.W is the work done by the system.The second law of thermodynamics defines that the total entropy in an isolated system will never decrease, and this is a constant only if all the process is reversible.

The third law of thermodynamics defines that the entropy in a system at the absolute zero temperature is a constant. Because the system here at zero temperature gets exists in the ground state. : Choose the correct option.

### What is the first law of thermodynamics answer?

What is the First Law of Thermodynamics? – The first law of thermodynamics states that the energy of the universe remains the same. Though it may be exchanged between the system and the surroundings, it can’t be created or destroyed. The law basically relates to the changes in energy states due to work and heat transfer. It redefines the conservation of energy concept.

 First Law of Thermodynamics The First Law of Thermodynamics states that heat is a form of energy, and thermodynamic processes are therefore subject to the principle of conservation of energy. This means that heat energy cannot be created or destroyed. It can, however, be transferred from one location to another and converted to and from other forms of energy.

To help you understand the meaning of the First Law, we can take the common example of a, In a Heat engine, the thermal energy is converted into mechanical energy and the process also is vice versa. Heat engines are mostly categorized as an open system.
