17.

How do we calculate the density of a liquid?

a)

We measure the mass of the liquid in a jug and then measure the mass of the jug on its own and subtract the mass of the jug to the liquid + jug. Then you measure how much liquid you have by pouring it into a measuring cylinder and then you divide the mass by the volume (how much liquid there is) and there is your density!

b)

We measure the mass of the liquid in a jug and then measure the mass of the jug on its own and multiply the mass of the jug to the liquid + jug. Then you measure how much liquid you have by pouring it into a measuring cylinder and adding water to it and then you divide the mass by the volume (how much liquid there is) and there is your density!

c)

We measure the particles of the liquid in a jug and then measure the mass of the jug on its own and divide the mass of the jug to the liquid + jug. Then you measure how much liquid you have by pouring it into a measuring cylinder and then you divide the mass by the volume (how much liquid there is) and there is your density!

d)

I don't know

18.

What is the first thing you do when lighting a Bunsen burner?

a)

You have to close the airhole

b)

Light it with matches

c)

Put it away

d)

Plug it into something

19.
