Does an increased volume of a substance increase its density?

Mass and velocity are the 2 factors used to calculate kinetic energy. the equation for kinetic energy is (1/2)mv^2. hope this !

The inference is supported by evidence in the graph is this is an exothermic reaction where the total release of energy equals a + c.

Repeated trials allow you to calculate a mean which can reduce the effect of random errors to make your results more precise.your results will also be reproducible therefore if someone else did the same experiment they'd get the same results which would make your results more reliable.
