Question

The diesel fuel cooler is being discussed. Technician A says that high-pressure fuel systems generate a lot of heat. Technician B says that temperature affects the density of the diesel fuel. Which technician is correct

Answer 1

Both the technicians are correct.

Step-by-step explanation:

As the pressure increases the temperature will also increase in accordance with the Boyle's law hence greater amount of heat is formed.

`Pressure\propto Temperature`

When the temperature increases the intermolecular spaces increase as the molecules of the fuel gain energy and their kinetic energy increases. This is limited to temperatures below dissociation/combustion temperature of diesel .
