Petroleum has less density than water. So, when fire streams are applied to the burning liquid surface at such an angle that hot and / or burning oil is forced over the edge of the tank, the oil then flows down the side of the tank and you are now confronted with a fire on the ground as well as the one in the tank.
<h3>What are the reasons not to use fire streams during deal with burning oil?</h3>
When you spray water on a regular fire, you're attempting to lower the flame's temperature and contain the fire.
Fuel for an oil fire is oil. Temperature and oxidizer are present in a fire (oxygen). Due to the fact that oil is lighter than water, an explosion may result if it floats above water while water sinks beneath oil.
Consequently, water shouldn't be used to put out oil fires.

J=joules, c=specific heat, q= energy, and the Tf and Ti are the final and initial temperatures cause I couldn't find a delta sign.
"Twice each second" means "2 per second". <em>Frequency = 2 Hz.</em>
<em>Period </em>= time for one bounce = <em>1 second</em>
Amplitude = distance between "not stretched" and "greatest stretch".
<em>Amplitude = 10 centimeters</em>
