The question asks about the average kinetic energy so it is not related with mass. We only need to compare the temperature. The higher temperature is, the higher kinetic energy is. So the answer is (2).
Answer:
Flash point of Lube Oil is around the 187°C mark,
Flash point of Biodiesel of 130°C
Flash point of Diesel Ranging from 52° to 96°
this is known as condensation when cold and warm temperatures meet
Answer:

Explanation:
Hello,
In this case, since a change in science is widely known to be considered as a subtraction between the the final and initial values of two measured variables and is represented via Δ, here the final density is 5.43 g/mL and the initial one was 3.21 g/mL, therefore, the change in density is:
