Reggie puts a beaker of ice and water on a hot plate, and the ice slowly begins to melt as shown in figure below. After a few minutes, only liquid water is in the beaker. Eventually, the water becomes hot and boils. The liquid water changes to water vapor, which is a gas. In what way is the liquid water different from the water vapor?

-Answer choices

The vapor particles have less energy.

The liquid particles move slower.

The liquid has a higher boiling point.

The vapor has a lower temperature.

Electromagnets coils of wire paper clips picked up 10 3 15 6 20 9 25 12 ms. owens' class was studying magnets. ms. owens showed her students how to make an electromagnet using a nail, a d-cell battery, and plastic coated wire. the students wrapped the wire around the nail and then attached the ends to the battery. when they were finished, they tested their magnets by investigating how many paperclips their magnets could pick up. they also tested whether they could increase the strength of their electromagnets by using more coils of wire. they recorded the class average of their results in the data table seen here. ms. owens asked her students to graph their data in a line graph. how should the students label the x-axis on their line graph? a) size of battery b) number of paper clips c) number of coils of wire d) strength of electromagnet
