Materials generally become warmer when heat is

• absorbed

• reflected

• transmitted

In an air-conditioned bus, water is slowly collected on the glass window panes. This process is best described by

• melting

• boiling

• evaporation

• condensation

Which one of the following conditions increases the rate of movement of particles in matter?

• increase in density

• increase in mass

• increase in volume

• increase in temperature

Which statement about the behaviour of the particles in a gas is not correct?

• They spread throughout the vessel in which they contained

• They are able to move at high speeds.

• They are arranged in regular patterns

• There are large spaces between the particles

Which of the following is an example of diffusion?

• Bubbles rising in a beaker of boiling water

• Steam condensing on a cold window

• Water spreading out on the surface of a table

• The spreading of the smell of flowers in a garden

An inflated balloons will shrink if placed in a refrigerator. This is because the lower temperature causes the gas particles in the balloons to move

• Faster and become closer together

• Faster and become further apart

• Slower and become closer together

• Slower and become further apart
