The amount of space between particles and their arrangement play a significant role in determining the state of matter—solid, liquid, or gas—and this relationship is closely linked to concepts of density, intermolecular forces, temperature, and pressure.
The relationship between the amount of space between particles and the state of matter is closely tied to the concepts of density and the arrangement of particles. The three primary states of matter are solid, liquid, and gas, and they exhibit different levels of particle spacing and arrangement:
Solid State: In a solid, particles are closely packed together in an ordered and fixed arrangement. The amount of space between particles is minimal, and they vibrate in place around fixed positions. Solids have a definite shape and volume due to the strong intermolecular forces that hold the particles together.
Liquid State: In a liquid, particles are still closely packed, but they have more freedom of movement compared to a solid. The intermolecular forces are weaker, allowing the particles to flow and move around one another. The amount of space between particles is larger than in a solid.
Gas State: In a gas, particles are widely spaced and move independently at high speeds. The amount of space between gas particles is much larger than in solids and liquids. Gases have neither a definite shape nor a definite volume, as they expand to fill the entire volume of their container.
This relationship between particle spacing and state of matter is described by the concept of density. Density is the mass of the substance per unit of the volume. Solids tend to have higher densities because their particles are densely packed, while liquids have lower densities due to the increased particle spacing.

Answer:
As the space changes between the particles, so does the state of matter. When the temperature of a solid is raised, the particles become more energetic, and they move farther and farther apart.
HOPE THIS HELPED!!!!!!!!!!!!!!XDDDD
B. The greenhouse effect
C. Solar radiation
D. Air conditioning
B. At room temperature, fats are solid and oils are liquid.
C. Fats are lipids and oils are carbohydrates.
D. Fats are triglycerides and oils are waxes.
Answer:
B. At room temperature, fats are solid and oils are liquid.
Explanation:
Fats and oils are one of the the three macronutrients (the other two are protein and carbohydrates).
However, fats and oils are different from each other: fats are mainly obtained from animals, while oils are mainly obtained from vegetable sources.
The major difference between fats and oil is that fats are composed of high amounts of saturated fatty acids which makes them solid at room temperature, while oils are composed of mainly unsaturated fatty acids which makes them liquid at room temperature.
Note that: in daily use the two terms may be used interchangeably.
It is B. When at room temperature fats are solid and oils are liquids.
