Although crystalline, colloid, glassy, amorphous, and plasma phases are thought to exist, the three basic phases of matter are solid, liquid, and gas (vapor). A phase change is defined as the transformation of a phase from one form to another. Thus, option 1. C, 2. A , 3. D, 4. B is correct.

What are different phases of matter?

Depending on the pressure and temperature circumstances, a given set of matter can change its state or phase, transitioning to different phases as these variables change to favor their existence.

The primary distinction between a substance's phase and state can be summed, For instance, a solid can convert to a liquid when the temperature rises.

A substance's phase describes its uniform chemical and physical qualities, whereas a substance's state describes its shape at a specific temperature and pressure.

Therefore, A phase change from a solid to a liquid represent melting.

Which state of matter does this model represent?
A} solid
B} liquid
C} gas
D} plasma

Answers

The state of matter represented by the above image is a liquid (option B).

What is matter?

Matter is the basic structural component of the universe. Matter usually has mass and volume.

Matter exists in three states namely;

Solid: the particles of a solid are very attracted to each other. They are close together and vibrate in position but don't move past one another.

Liquid: In a liquid, the particles are attracted to each other but not as much as they are in a solid.

Gases: In a gas, the particles have very little attraction to each other. They are very far apart compared to the particles in a solid or liquid, and are constantly moving. The particles don't interact with one another but just hit and bounce off of each other when they collide.

Based on the particles of the substance in the image above, one can observe that they are closely but not tightly packed, which suits the description of liquid state.

Therefore, the particles of the substance in the model represent a liquid.

an example of how water moves from
the biotic part to the abiotic part of an
ecosystem.

Answers

• Moving from abiotic to biotic: absorption by root hairs of plants
• Moving from biotic to abiotic: transpiration. Water evaporates from the leaves of plants.

One of the important examples of how water moves from the biotic part to the abiotic part of the ecosystem includes transpiration of water from the surface of the leaves of plant.

What is Transpiration?

Transpiration is the loss of water in the form of vapors from the surface of leaves of plant. Transpiration of water takes place from the stomata of plant cells.

Stomata are the specialized cells present on the surface of leaves which are covered by the guard cells that regulates the opening and closing of stomata and hence the movement of water from the leaf surface.

In transpiration, water from plant, a biotic part of ecosystem is lost in the form of vapors to the atmosphere, i.e., an abiotic component of ecosystem. The rate of transpiration is regulated by factors such as sunlight, concentration of ions like sodium and potassium, presence of starch.
