In which phase of matter is there the least spacing between particles? (a)  

• Solid

• Liquid

• Gas

• Plasma

Answer explanation

In solids, particles are closely packed together in a fixed arrangement, resulting in the least spacing between them. This contrasts with liquids, gases, and plasma, where particles are more spread out.

In which phase of matter is there the most potential for movement? (a)  

• Solid

• Liquid

• Gas

• Plasma

Answer explanation

In gases, particles are far apart and move freely at high speeds, allowing for the most potential movement. In contrast, solids have fixed positions, and liquids have more restricted movement, making gas the correct answer.

In which phase of matter is there the most potential for movement? (a)  

• Solid

• Liquid

• Gas

• Plasma

Answer explanation

In gases, particles are far apart and move freely, allowing for the most potential movement. In contrast, solids have fixed positions, and liquids have limited movement compared to gases.

Which phase of matter does not have a definite shape yet the particles will not fill the container? (a)  

• Solid

• Liquid

• Gas

• Plasma

Answer explanation

Gas does not have a definite shape and will expand to fill its container. However, in a confined space, gas particles will not fill the entire volume if the pressure is low or if there are obstacles, unlike liquids.

In terms of spacing, what is necessary to change from a solid to a liquid?

• Increase in spacing

• Decrease in spacing

• No change

• Add heat

Answer explanation

To change from a solid to a liquid, the particles must move further apart, which requires an increase in spacing. This allows the particles to overcome their fixed positions and flow, characteristic of liquids.

In terms of spacing, what is necessary to change from a liquid to a gas?

• Increase in spacing

• Decrease in spacing

• No change

• Add heat

Answer explanation

To change from a liquid to a gas, the particles must move further apart, which requires an increase in spacing. This allows the particles to overcome intermolecular forces and enter the gaseous state.

In terms of spacing, what is necessary to change from a gas to a liquid?

• Increase in spacing

• Decrease in spacing

• No change

• Add heat

Answer explanation

To change from a gas to a liquid, the particles must come closer together, which means there is a decrease in spacing. This allows the attractive forces between particles to take effect, leading to condensation.
