Question

You are heating water in a teapot on the stove. The water starts to boil, creating steam that makes the teapot whistle. Which of the following describes what happens to the water molecules during this process?

Answer 1

What are your options?

Answer 2

there is no options they want it to solve it

Answer 3

"Which of the following describes what happens to the water molecules during this process?"

Answer 4

It sure looks like they should have some choices following the question...

Answer 5

Most of the bubbles start at the bottom, because that's where the heat is. The more heat you apply, the more bubbles you will get. The water is turning into a gas very quickly, and lots of bubbles form, and all try to rise to the surface at once

Answer 6

Well, a generic answer is that the water molecules are gaining energy from the heat that is being applied to the teapot. As they gain energy they move faster and collide more...spreading out. As the water is heated it eventually goes through a phase change (liquid to gas). At this point the gas wants to expand so it's only way to do that is to escape through the openings of the teapot's whistle.

Answer 7

im sorry i put the wrong ?....it was suppose to be this one

Diego is working on a problem about net forces. In the problem, Meredith is applying a force of 5 N while Lanaya is applying a force of -7 N. Diego assumes that Meredith is applying a greater force than Lanaya. Explain why Diego is wrong and why he may have thought this.

Answer 8

Ok, that one's pretty simple. Diego assumes that because Meredith's force is mathematically larger than Lanaya's (based on the sign), that her force is greater. The mistake Diego is making is in thinking that the sign is an indication of magnitude. The sign is really an indication of direction.
