Problem Analysis:
The task involves identifying the correct state of matter (solid, liquid, gas, or plasma) based on specific properties described in each question. Additionally, there is a question about the energy required to change a substance from one phase to another. Let's solve each question step by step.
---
Question 1:
This state of matter has definite volume but takes the shape of its container.
-
Solid: Has both definite shape and definite volume.
-
Liquid: Has definite volume but takes the shape of its container.
-
Gas: Has neither definite shape nor definite volume.
-
Plasma: A highly energetic state of matter, not typically described by these properties.
Answer:
C. Liquid
---
Question 2:
This state of matter does not have definite shape or volume.
-
Solid: Has definite shape and volume.
-
Liquid: Has definite volume but takes the shape of its container.
-
Gas: Has neither definite shape nor definite volume.
-
Plasma: Similar to a gas but with unique properties (highly ionized).
Answer:
B. Gas
---
Question 3:
This state of matter has definite shape and definite volume.
-
Solid: Has both definite shape and definite volume.
-
Liquid: Has definite volume but takes the shape of its container.
-
Gas: Has neither definite shape nor definite volume.
-
Plasma: Does not have a definite shape or volume.
Answer:
C. Solid

Question 4:
Atoms in this state of matter are held tightly in place by the attraction between the particles.
-
Solid: Particles are tightly packed and held in fixed positions due to strong intermolecular forces.
-
Liquid: Particles are close together but can move past each other.
-
Gas: Particles are far apart and move freely.
-
Plasma: Particles are highly energized and do not maintain fixed positions.
Answer:
D. Solid
---
Question 5:
In this state of matter, particles have enough energy to slip out of their ordered arrangement, allowing them to "flow."
-
Solid: Particles are fixed in position and cannot flow.
-
Liquid: Particles can slide past each other, allowing the substance to flow.
-
Gas: Particles are too far apart and move randomly, not in an ordered flow.
-
Plasma: Particles are highly energized but do not flow in an ordered manner.
Answer:
C. Liquid
---
Question 6:
The amount of energy required to change a substance from the solid phase to the liquid phase.
-
Boiling point: The temperature at which a liquid turns into a gas.
-
Heat of fusion: The energy required to change a solid into a liquid without changing its temperature.
-
Melting point: The temperature at which a solid turns into a liquid.
-
Heat of vaporization: The energy required to change a liquid into a gas.
Answer:
B. Heat of fusion
