Answer:
b-energy is not exchanged
Explanation:
An isolated system is a thermodynamic system in which neither energy nor matter is exchanged with the surroundings.
As such the best statement that will fill the box under an isolated system is that energy is not exchanged.
- In an open system, both matter and energy are exchanged with the surrounding.
- A closed system is one in which energy transfer is permissible but matter is not exchanged.
- Energy cannot be created nor destroyed in any system. They are simply transformed.

I believe the correct answer from the choices listed above is option B. In a food chain. it is the producers trophic level that contains <span>the greatest amount of energy since it is the very start of the chain. Most of the energy are being stored and passed to the next organism. Hope this answers the question.</span>
Answer:
Work done by the gardner is 500 J
Explanation:
As we know that the gardner apply force perpendicular upward by magnitude 300 N and along the floor horizontal force is 100 N
so we have
now the displacement of the gardner along the floor is
now work done is given as
so we have
In this area the convection is taking place inside the water which is inside the utensils.
<u>Explanation:</u>
- Convection is the type of heat transfer method which is usually taking place through the liquid and gases. In this convection process, the liquid acts as the medium for the heat transfer.
- From the given picture we can see both convection and conduction. The conduction process which occurs in the solid objects. Here the heat is directly given to the pan which is a solid conductor so the pan conducts the heat.
- Inside the pan there happens to be the liquid which favors the convection process and again the eggs are heated by the conduction process as the outer part of the egg is solid.
