Which is the higher temperature? (Assume temperatures to be exact numbers.)(a)1.)265°C or 265°F?2.)265°C3.)265°F 4.)They are the

vazorg [7]

Remember the following formulas to convert temperatures between Farenheit and Celsius:

$\begin{gathered} \text{ Farenheit to Celsius:} \\ C=\frac{5(F-32)}{9} \\ \\ \text{ Celsius to Farenheit:} \\ F=\frac{9}{5}C+32 \end{gathered}$

Convert all the temperatures to Celsius to compare them.

Convert 265ºF to Celsius:

$\begin{gathered} C=\frac{5(F-32)}{9} \\ \\ =\frac{5(265-32)}{9} \\ \\ =129.444... \end{gathered}$

Then, 265ºF is equal to 129.444...ºC. Then, 265ºC is higher than 265ºF.

The correct choice is option 2) 265ºC.

Part b)

Convert 370ºF to Celsius:

$\begin{gathered} C=\frac{5(F-32)}{9} \\ \\ =\frac{5(370-32)}{9} \\ \\ =187.777...ºC \end{gathered}$

Then, 370ºF is equal to 187.777...ºC. Then, 200ºC is higher than 370ºF.

The correct choice is option 2) 200ºC.

The following statements regarding the exhaust gas recirculation (EGR) valve are all correct except:

elixir [45]

Answer:

B. Some systems monitor EGR operation using a manifold absolute pressure (MAP) sensor.

Explanation:

The Manifold Absolute Pressure (MAP) sensor is a device used to measure absolute pressure inside the engine, it is used to calculate gas quantity needed to be injected into the cylinder and also for engine load input by the powertrain control module (PCM).

It is not used with the EGR as a monitor.
