Question

What is the first law of thermodynamics and how does it apply to chemistry?

Answer 1

Hint: The study of heat and the phenomena linked with it is known as thermodynamics. The zeroth, first, and second laws of thermodynamics are the three laws of thermodynamics. The concept of temperature is given by the zeroth law of thermodynamics, and temperature controls the flow of heat, which always travels from a hotter to a colder body. The opposite of it cannot happen on its own, as the second law clearly explains.

Complete answer:
The first law of thermodynamics states that in a closed system, mass energy is always conserved (yes, such as the universe). In any chemical or nuclear reaction, mass energy is always equal.
Explanation:-
In a closed reaction vessel, the amount of energy in the reactants must always match the amount of energy in the products in all chemical and nuclear processes.
In most spontaneous reactions, the energy can be transferred from potential to heat or kinetic energy. Kinetic energy or order is converted to potential energy in some reactions.
Although mass can be converted to energy in nuclear energy, the total mass and energy must always stay the same. In a closed system, no known natural laws or processes may either make or destroy matter or energy.

Note:
The first law of thermodynamics has restrictions. According to the law, anytime a system goes through a thermodynamic process, it always maintains a specific energy balance. The first law, on the other hand, fails to account for the feasibility of the system's process or change of state. When a metallic rod is heated at one end but not the other, for example, the first law fails to explain why heat transfers from hot end to cold end. The first law merely measures the amount of energy transferred during this process. The second law of thermodynamics is the criterion for determining the feasibility of various processes.
