For everything I answer for y’all can y’all do this for me plz

GREETINGS!

in phenomenin 3

phase change vapourization

1st liquid

2nd gas

When u give heat to the liquid their Kinetic energy increases when their kinetic energy increases they collide with eaxhother and move farther away resulting in escape of particles in from of gases

In phenomenon 4

phase change freezing

1st liquid

2nd solid

when temperature decrease the kinetic energy of particles decreases in result particles come close to each other and they convert into solid that is freezes

HOPE IT HELPS

To find the density, I always say, "density is a broken heart". The reason is that it's mass over volume. 

Ex: D = m/ v

In your problem, it's:

D = 632g/ 680 mL

To find the density of the Linseed oil, divide the volume by mass.

680mL/ 632g = 1.07

Now that you have your answer, you need to have the correct units. Since you have two different units, you'd use those both. So, your answer will be grams over mL.

The density of the Linseed oil is 1.07g/mL

I hope I helped :)
