<span>As a solid element melts, the atoms become <u>more separated</u> and they have <u>less</u> attraction for one another.
When a solid element starts melting, it means that it is using up a lot of energy it has stored. And when there is a lot of energy being used up, its particles are vibrating fast, and becoming more and more separated. So obviously, if these atoms are far from each other, they aren't going to attract.</span>
Answer:
We could plant more trees :)
Explanation:
Trees producer oxygen AND absorb carbon dioxide, something our earth has too much of, thanks to humans
I think the volume should be still 14.3L. In this question, the gas is being held in a tank. The tank has a constant volume. The gas in the tank has the property to fill the space. So when the temperature changes, the pressure changes too. But the volume doesn't change.
In water particles a much closer together and they can quickly transmit the vibration energy from one particle to the next. This means the sound wave travels over four times faster than it would in air but a takes a lot of energy to start the vibration.
Hopefully This Helped You!

The law for universal gravitation is
F=G(m1m2/d^2)
