Q

How are the particles arranged in a liquid?

Q

Why does a smell of gas take so long to travel?

A

Because gas particles bump into other air particles on its way

17
Q

Why is diffusion in liquids very slow?

A

Because particles in liquids move a lot slower than gas particles

18
Q

What is a solute?

A

The substance that is being dissolved

19
Q

What is a solvent?

A

The liquid the solute dissolves in

20
Q

What is a solution?

A

The liquid formed by combining the two

21
