First law of thermodynamics
Explanation:
The statement that energy can that "energy can neither be created nor destroyed but changed or transformed from one form to another" is the first law of thermodynamics.
- Thermodynamics deals with energy changes that accompanies a process.
- we can deduce from the first law that energy is conserved in every system.
- Energy is simply not produced by converted from one form to another in nature.
- For example, the heat energy we derive from eating food is due to the chemical energy stored in them.
- The chemical energy is converted into heat energy during digestion.

Answer:
Silver is a malleable and ductile metal having atomic number 47 and symbol Ag. Gold on the hand has atomic number 79 and symbol Au. It is also ductile and malleable. Both are soft and lustrous in nature. Both are transition metals.
Bronze is an alloy of majority of copper and some amount of tin. Formation of alloy enhances the properties of the metal and its industrial use. Bronze is harder than copper and easily fusible and easy to cast. It is resists corrosion.
Silver and gold have different atomic numbers, different colors. Both are transition elements where as Bronze is an alloy.
They are the standard system used by scientists worldwide, and
officially by almost all nations of the world. So if you describe a
measurement in terms of SI units, there's less chance that you'll
need to explain the measurement to anyone who reads it ...
most scientists and common people worldwide will understand
what your number means.
