Question 4 of 32

1

Which of these solid facts is incorrect?

Select one or more of the following:

Solid (s) particles are strongly attracted to one another and are arranged in a lattice form. Thus, they keep their own shape.
Solid particles can easily move around within the solid.
A solid cannot be compressed.

Explanation

Question 5 of 32

1

Which of these liquid facts is incorrect?

Select one or more of the following:

The attractive forces between liquid particles is more easily broken since the particles have more kinetic energy. This means they are more mobile than solid particles - liquids can flow, but still take the shape of their container.
Particles at the surface of a liquid can break away and escape - a liquid can evaporate.
There is a vast space between the particles in a liquid, so they can easily be compressed.

Explanation

Question 6 of 32

1

Liquids that mix with each other are immiscible. True or False

Select one of the following:

True
False

Explanation

Question 7 of 32

1

Which of these gas facts are incorrect?

Select one or more of the following:

Gas particles have even more kinetic energy than liquid particles and there is very little attraction between them. The particles move at very high speeds and independently of one another, so they fill any available space.
Gas particles collide with the surface of their container and exert pressure (force per unit area)
Gases do not mix readily with other gases, because of the particle's rapid motion.

Explanation

Question 8 of 32

1

As matter is heated... Choose the part of the process which are true.

Select one or more of the following:

As matter is heated, the particles gain kinetic energy, transferred from heat energy, and so are able to move faster.
As a solid is heated, the vibrations of its particles decrease, until eventually the particles are able to break away from each other into a sparse collection.
The temperature at which all solid becomes liquid is the solid's melting point.
Similarly, the particles in a liquid move faster as they are heated, until the particles break free of the liquid to become a gas. This temperature is called the liquid's boiling point.

Explanation

Question 27 of 32

Which of these are correct?
