Measuring mass

Your teacher gives you a sample of liquid and ask you to measure its mass. Which instrument should you use?

• Test tube.

• Scale.

• Ruler

• Thermometer

This picture shows the following state of matter:

• Solid.

• Gas.

• Solid and gas.

• Liquid and gas.

Camila wants to know the mass of a liquid that is inside a glass. After measuring it, she records the following numbers.

The mass of the liquid is:

• 50g.

• 30g.

• 20g.

• 80g.

A book, the oxygen that we breathe, and the water that we drink are matter. We can say that matter is:

• Everything that has mass and volume.

• Everything that has a definite shape.

• Everything that has mass, even though it does not have volume.

• Everything that flows.

Matter has specific characteristics according to its state. A solid state of matter does not flow as liquid and gases do because:

• Their particles can move past one another.

• There is a lot of space between their particles.

• Their particles are close together and they can only vibrate.

• There is a lot of space between their particles and they can move around freely.

A teacher needed 500 g of ice to carry out an experiment. In order to do this, he has to put in a freezer:

• 500 g of water.

• 1000 g of water.

• 250 g of water.

• 550 g of water.

Analyze the following picture. In relation to the mass of these objects, it can be said that:

• I and II have greater mass than III.

• III has less mass than I.

• III has greater mass than I and II.

• III has the same amount of mass as I and II.
