The change of the statue of liberty from copper to green is an example of a chemical change.
<h3>Physical and chemical change</h3>
A physical change does not involve the formation of new substances and the composition of the substance does not change. However, in a chemical change, a new substance is formed and the composition of the substance changes.
The statement that reflect a chemical change is;
- The Statue of Liberty’s metal tarnishes from copper to green.

Divide 180kg and 90m3 and your density will be 2kg/m3
This problem applies Hess' Law to come up with the final reaction from a series of reactions given. Equation (1) stays as it is. Equation (2) should be inverted and divided by 2. Equation (3) is simply divided by 2. The energies should also correspond to the operations. Adding the net energies of each reaction, the total energy is 155.65 kJ. Hence, the answer is A.
We know that the particles in a matter have energy. They have kinetic energy, potential energy, chemical energy, electrical energy etc.
When we give heat to a matter it gains energy and there is an increase in its internal energy. Or we can say that particles in a matter have more energy at higher temperature than particles in a matter at low temperature
As ice is formed below zero degree celsius so the particles in ice must have lesser energy than water at higher temperature.
Thus true statement will be
The particles in boiling water have more energy than the particles in ice water do.
the answer is b it is composed of protons and neutrons.
hope this helped
