A rumor spread faster in a classroom where students are confined to desks than in a gym where all of the students can move around freely.

The same applies to conductivity between metals and ionic solids because metals have more close particles.

Conductivity is the process by which a material is able to transfer electric charge or heat from one point to another without the actual movement of the particles of the substance.

The conductivity of substances varies from one substance to another.

The conductivity of solids is greater than the conductivity of that of other substances.

The conductivity of substances increases with a decrease in the distance between the particles of the substance.

Thus solids that have the closest particles have the highest conductivity.

Liquids have medium conductivity.

Gases have the least conductivity because they have the most spaced-out particles.

The melting of a glacier is an example of interaction among;

Hydrosphere, asthenosphere, atmosphere

Explanation:

The melting of a glacier is an example of the interactions among the Earth's cryosphere and hydrosphere

The cryosphere is described as the portions on Earth where water appears in solid (frozen) form such as glaciers, frozen grounds, snow covered land, sea ice, ice sheets, river ice, ice caps, etc.

The hydrosphere is all the forms water on a planet including, ice, liquid water and water vapor, therefore, the cryosphere is a part of the hydrosphere

The geosphere comprises the Earth's interior, including the asthenosphere, which is fluid and hot and therefore spread heat through both conduction and convection to the hydrosphere that raises the ocean temperatures and lead to glacier melting

The green house effect in the atmosphere results in global warming that raises the average temperature of the Earth which in turn raises the temperature of the oceans and the troposphere, resulting in melting of a glacier

Therefore, the melting of a glacier is an example of interaction among the hydrosphere, asthenosphere, and, atmosphere

Answer:

D. There is no net change to the system

Explanation:

Equilibrium means "equal". In a chemical system, changes occur in substances called the reactants to produce another substance called the products. These changes from reactants to products and vice versa occur at an uneven rate until EQUILIBRIUM is reached.

In other words, equilibrium is attained when the reactants and products are formed at an equal or constant rate i.e. There is no net change to the system. For example, in the chemical system below:

A + B ⇌ C + D

This system is said to be at "EQUILIBRIUM" if the rate of reaction of the reactants (A and B) is equal to that of the products (C and D). That is, there is no net change (difference) in the reaction rate.

Answer:

1. A

2. D

3. E

4. B

5. C

Explanation:

1. Plants are known as producers since they produce energy for themselves through photosynthesis.

2. The rabbit is a primary consumer since it’s herbivore and only feeds on producers for energy.

3. The tiger is a carnivore, and preys on other consumers for energy.

4. A human is an omnivore since it can gain energy from both producers and consumers.

5. Bacteria are know as decomposers since such category of organisms break down other organisms to gain energy.

The combustion temperature of a material determines whether a material melts or burns

Materials whose combustion temperatures are lower than their melting point gets burnt instead of melting, because before the temperature of the material is raised up to the melting point temperature,  the materials gets combusted at a lower temperature known as the combustion temperature

Melting is physical change and is controlled by the physical property ( melting point ) while burning is chemical change which is irreversible.

Hence we can conclude that The combustion temperature of a material determines whether a material melts or burns

Answer:

Ionosphere.

Explanation:

The atmospheric layer that is represented by F is known as IONOSPHERE.

The characteristics of Ionosphere

1. It is considered to be located in the upper layer of the earth's atmosphere due to the location of region F.

2. It is ionized by solar radiation that contains an electrical charge.

3. It functions as a reflector. This can be observed in radio waves broadcasting.

Answer:

Explanation:

The process is photosynthesis as plants need carbon dioxide and humans need oxygen so plants release oxygen which humans breath/take in and plant/trees take in carbon dioxide which humans release.

The natural process which removes  carbon dioxide from the atmosphere is photosynthesis.

It is defined as a process by which plants and other photosynthetic organisms convert the light energy in to chemical energy  through the process of cellular respiration.

Some of the energy which is converted  is stored in molecules of carbohydrates like sugar and starches  which are made up of from carbon dioxide and water . Photosynthetic organisms which can perform photosynthesis  are algae and cyanobacteria. Photosynthesis is largely responsible for producing and maintaining the content of oxygen in earth's atmosphere.

The process begins with proteins absorbing light energy  which are called reaction centers and contain a green pigment which is called chlorophyll . In plants ,these pigments are present inside organelles called chloroplasts while in bacteria they are present in plasma membrane.
