summarize your observations about the relationships between molecular mass (heavy vs light), kinetic energy, particle speed, and temperature

See explanation

Explanation:

Given that the kinetic energy of particles is obtained from; Ek = 1/2 mu^2. The speed of particles is given by c = [3RT/M]^1/2.

From what we can see in the graphs with heavy particles, they only have higher peaks while the lighter particles have lower peaks of kinetic energy and  particle speed.

From the graphs and the temperatures used, it is evident that the shape of the graphs were almost the same. Temperature appears not to have any outstanding effect on it.

specific latent heat of fusion, lf, of a substance is defined as the amount of heat required to change a unit mass of the substance from solid to liquid state, without any change in the temperature.
