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

sodium (na), for example, has one electron in its valence shell. this is an unstable state because that valence shell needs eight electrons to be full. in order to fill its valence shell, find a way to add seven electrons to its valence shell

well in order to answer this question you have to provide more information < 3

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
