Answer:
Yes, the heat that flows into the system is used to change the internal energy of the gas and becomes work done by the piston.
Explanation:
First law of thermodynamics known as Law of Conservation of Energy, states that energy can neither be created nor destroyed; energy can only be transferred or changed from one form to another.
The first law of thermodynamics states that the change in internal energy of a system equals the net heat transfer into the system minus the net work done by the system. In equation form, the first law of thermodynamics.
This is the first law of thermodynamics
ΔE= Q− W
ΔE= change internal energy of the system.
Q= heat transfer into the system
And
W= work done by the system.
Rewriting the equation
ΔE= Q− W
Q=ΔE +W
Show that the heat flowing l into the system is transferred to the internal energy of the system and the work done by the piston
So the third option is correct

Zero latitude gets the most direct sun all year around. That's the equator.
The picture you attached has nothing to do with this question.
Answer: 2250 tours
Explanation:
We have the following data:
Speed of light: 
Circumference of the equador: 
The time in which light turns around equator: 
We need to find how many tours does light do around the equator in 
Let's begin by the expression of the speed, which is a relation between the traveled distance (
) and time:
(1)
Isolating
:
(2)
(3)
(4) This is the distance light travels in 5 min.
Now we need to know to how many tours is this distance equivalent, we can know this by a Rule of three:
1 tour ----
(circumference of the equator)
? tour ---- 
Then:


This is the count of tours in 5 minutes.
