Question
Please someone help me with these questions soon as possible1. What is the zeroth law of thermodynamics? Give an example of this application. 2. What is the first law of thermodynamics? Give an example of this application 3. As illustrated in the following Figure 1, water circulates between a storage tank and a solar collector. Heated water from the tank is used for domestic purposes. Considering the solar collector as a system, identify locations on the system boundary where the system interacts with its surroundings and describe events that occur within the system. Repeat for an enlarged system that includes the storage tank and the interconnecting piping. Hot water Hot water storage Solar collector tank Circulating pump Cold water return Figure 1 A system consisting of liquid oxygen in equilibrium with oxygen vapor. How many phases are present? The system undergoes a process during which some of the liquid is vaporized. Can the system be viewed as being a pure substance during the process? Explain. Why is it incorrect to say that a system contains heat? What form does the energy balance take for an isolated system? Interpret the expression you obtain. Each line in the following table gives information about a process of a closed system. Every entry has the same energy units. Fill in the black spaces in the table. Process 4. 5. 6. 7.

Explanation / Answer
If two bodies are in thermal equilibrium with third body, they are also in thermal equilibrium with each other. This is known as Zeroth Law of thermodynamics.
When a body A is in thermal equilibrium with a body B, and also separately with body C then body B and body C will be in thermal equilibrium with each other. This is known as Zeroth Law of thermodynamics.
Two thermometers measuring same body temperature.
First Law of Thermodynamics states Energy can be changed from one form to another form, but it cannot be created or destroyed. The total amount of energy and matter in the Universe remains constant.The First Law of Thermodynamics (Conservation of energy) states that energy is always conserved, it cannot be created or destroyed.
Rubbing hands together generates heat on our palms. This is not actually creating energy. The work of our muscles takes the chemical energy of our body, changes it to work energy in our muscles, and then into friction (heat) energy in our skin. Energy is always conserved.
Q = dU + W , heat transfer to system is equal to sum of the change in internal energy of system and work done by system
