Which best explains the relationship between evaporation and temperature?
a)a liquid evaporates slower at lower temperatures because the molecules are more spread apart and are not pushed as easily from the liquid’s surface.
b)a liquid evaporates faster at lower temperatures because the attractions are decreased and more particles can escape the surface of the liquid.
c)a liquid evaporates slower at higher temperatures because the vapor pressure of the liquid is higher, so fewer molecules can escape the surface.
d)a liquid evaporates faster at higher temperatures because more particles have a higher speed and can overcome attractions in the liquid.

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
