1 point A student team heated two solid substances, A and B, and collected data
about their temperatures over time. Using their data, the students made a
graph, numbering that segments that represented a phase or a phase
change for each substance. Their graph is shown below. Which substance
has a lower specific heat capacity while it is a solid, and how does the
graph indicate this?
Heating of Two Substances
Substance A
Substances
Time
O Substance A because segment 1 is steeper than it is in substance B
O Substance B because segment 3 is steeper than it is in substance A
O Substance A because segment 2 begins earlier than it begins in substance B
O Substance because segment 4 occurs at a lower temperature than in substance A

Which explanation is true about what happens to a ray of light when it strikes a mirror? a. a light ray is transmitted toward a mirror at a certain angle. the light ray is then reflected by the mirror at an equal angle but in the opposite direction of the transmitted ray. b. an incident ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then reflected at an angle equal to the angle of incidence but on the opposite side of the perpendicular line. c. a reflecting ray strikes a mirror at an angle with a line perpendicular to the mirror. the light ray is then refracted at an angle equal to the angle of the reflecting ray and on the same side of the perpendicular line. d. an incident ray strikes a mirror at an angle with a line parallel to the mirror. the light ray is then transmitted at an angle equal to the angle of incidence but on the opposite side of the parallel line. you so much! : -d take the time to try and answer correctly.

16. in a reaction that has reached equilibrium, a. the forward and reverse reactions are occurring at the same rate. b. the reactants and products are in equal concentrations. c. the forward reaction has gone further than the reverse reaction. d. there are equal numbers of atoms on both sides of the equation. e. a, b, and d are correct.
