Semester 2, Storyline 2, Investigation 4 Review Game

Solids, liquids and gases all have kinetic energy due to motion of their atoms or molecules. How is kinetic energy measured?

• By calculating the volume.

• By measuring the temperature.

• By measuring the pressure.

• By measuring the number of particles.

Pressure is a measure of the __________.

•    space between particles

• size of the container

• speed of the particles

• number of collisions

Pressure is affected by which of the following? Select all that apply.

•   temperature

• volume

• number of particles

• cubic structure

Which of the following will decrease the pressure of a gas in a closed container?

• increasing the number of molecules

• increasing the temperature

• increasing the volume

A drop of Substance A evaporates in 30 seconds while it takes a drop of Substance B 3 minutes. From the observations, it can be concluded that the boiling point of Substance A is _______ than Substance B and the intermolecular forces in Substance A are _______ than in Substance B.

• higher; stronger

• higher; weaker

• lower; stronger

• lower; weaker

Water has a number of unique properties. Why is ice less dense than liquid water?

• Solid water molecules pack together closer than liquid water particles.

• Cold liquid water particles move slower than warn liquid water particles.

• Solid water molecules must form hexagons which take up more space.

• Solid water is actually a higher temperature than liquid water.

• ionic bond

• metallic bond

• covalent network bond

• non-polar covalent bond

Which property of water allows for water bugs to skim along the surface? 

• density
