15 ! a certain substance is a solid at 15°c. sarah heated a sample of the solid substance in a beaker using a bunsen burner during science class. she and her partner recorded the temperature at one-minute intervals. their data is recorded in the table below. based on the girls' data, when was the kinetic energy of the substance the greatest? a) at 15° c b) at 60°c. c) when they started the heating process. d)  during the period when the substance remained at 54°c.

Base your answer on the information below and on your knowledge of chemistry. nitrogen dioxide, no2, is a dark brown gas that is used to make nitric acid and to bleach flour. nitrogen dioxide has a boiling point of 294 k at 101.3 kpa. in a rigid cylinder with a movable piston, nitrogen dioxide can be in equilibrium with colorless dinitrogen tetroxide, n2o4. this equilibrium is represented by the equation below. 2no2(g) n2o4(g) + 58kj at standard pressure, compare the strength of intermolecular forces in no2(g) to the strength of intermolecular forces in n2(g).
