Boiling point experiment summary
WebApr 10, 2024 · They were modeled as vapors with a temperature just above the boiling point of ammonia and velocities of 0.01 m/s. To determine the mass flow rate, the initial puff mass and release time were needed. To find the puff mass, the mass of ammonia in the bund at the end of the release was subtracted from the total ammonia released, thus … WebMelting and boiling point examples. When we look at the melting/boiling points of elements, there are some general trends that emerge. Groups 15, 16, and 17. Melting and boiling point increases as you move down a group. Increasing atomic size → increases forces between particles → harder to melt/boil.
