FAQs on Maharashtra Board Class 12 Solutions for Chemistry Chapter 4 Chemical Thermodynamics - PDF
1. What are the factors that affect Internal Energy?
There are two ways on how internal energy is affected:
Work:
Energy exchanged between a system and its surroundings is what is referred to as a system's work. External elements, such as an external force, volume, change in temperature, etc., influence the work.
Heat:
The kinetic energy of a substance's molecules is referred to as heat in thermodynamics. The fundamentals of thermodynamics and heat enabled process designers and engineers improve their systems and economically capture the energy of chemical reactions.
2. What is enthalpy of fusion?
The term "heat of fusion" refers to the energy required to melt a specific mass of a solid at that solid's melting point temperature. On the other hand, it also represents the energy lost when a specific mass of liquid hardens. For instance, water has an 80 calorie heat of fusion per gram.
3. What are the two types of thermodynamic systems?
There are two types of thermodynamic systems-
Open System:
Systems that allow both the exchange of matter and energy are referred to as open systems. For instance, when water gets heated using the stove, the container behaves like an open system since heat energy is being supplied from outside and the substance discharged is water vapor.
Closed System:
A closed system is one in which only energy, not matter, is exchanged with the environment. Another way to put it is that in a closed system, the amount of matter is always the same and the only variable is the system's energy.
4. What is the first law of chemical thermodynamics?
The conservation of energy is the first law of thermodynamics. This law states that when a system transitions from an initial state to a final state, the total energy of the system and its surroundings stays constant.
