fuel.

2. The safety use of light fuel oil determined by flash point.
3. The petroleum gases may be used as fuel for power stations.
4. Oiesel index used for evaluation of paving asphalt.

Answer 1

Solution

True

The Reid vapor pressure (RVP) is frequently used as an indication of the volatility of liquid hydrocarbons. .

Answer 2

True

The flash point is determined by heating the sample of fuel in a container and passing the flame over the surface of the sample. If the temperature is at or above the flash point, the vapor will ignite and an easily detectable flash can be observed
