Answer:
Explanation:
t1 = 1000 F = 1460 R
t0 = 80 F = 540 R
T2 = 3600 R
The working substance has an available energy in reference to the 80F source of:
B1 = Q1 * (1 - T0 / T1)
B1 = 100 * (1 - 540 / 1460) = 63 BTU
The available energy of the heat from the heat wource at 3600 R is
B2 = Q1 * (1 - T0 / T2)
B2 = 100 * (1 - 540 / 3600) = 85 BTU
The reduction of available energy between the source and the 1460 R temperature is:
B3 = B2 - B1 = 85 - 63 = 22 BTU
Technician B only is right, who says that to avoid warping the cylinder head, the engine must be cold before removing it.
<h3>What is the cylinder head doing in my car?</h3>
The main task of the cylinder head is to close the discharge chamber of the engine from the top. The upper part of the engine is reached the cylinder head, while the lower part is the engine partnership.
The cylinder head sits on the engine and shuts off the combustion chamber. The gap that remains between the cylinder head and the engine is achieved by the head gasket.
<h3>How to recognize signs of possible defects</h3>
If you notice abnormalities in the functioning of your engine, it is advisable to contact a garage as soon as feasible to prevent further injury.
- The signs of cylinder head flaws include:
- You notice a power loss of the machine
- The cooling water temperature is in the red area
- You see oil in the cooling water
- You must supply water and oil after just a short time
- You notice a bad cold start behavior

Answer:
Do heavier cars really use more gasoline? Suppose a car is chosen at random. Let x be the weight of the car (in hundreds of pounds), and let y be the miles per gallon (mpg)
Explanation:
If you suspect anything is wrong with it such as it not working or before using one of them
