Answer:

Three States of Matter

 

 

Learning Objective

Describe the three states of matter

Key Points

Matter can exist in one of three main states: solid, liquid, or gas

The states of matterThis diagram shows the nomenclature for the different phase transitions.

Solids

A solid’s particles are packed closely together. The forces between the particles are strong enough that the particles cannot move freely; they can only vibrate. As a result, a solid has a stable, definite shape and a definite volume. Solids can only change shape under force, as when broken or cut.

In crystalline solids, particles are packed in a regularly ordered, repeating pattern. There are many different crystal structures, and the same substance can have more than one structure. For example, iron has a body-centered cubic structure at temperatures below 912 °C and a face-centered cubic structure between 912 and 1394 °C. Ice has fifteen known crystal structures, each of which exists at a different temperature and pressure.

A solid can transform into a liquid through melting, and a liquid can transform into a solid through freezing. A solid can also change directly into a gas through a process called sublimation.

Liquids

A liquid is a fluid that conforms to the shape of its container but that retains a nearly constant volume independent of pressure. The volume is definite (does not change) if the temperature and pressure are constant. When a solid is heated above its melting point, it becomes liquid because the pressure is higher than the triple point of the substance. Intermolecular (or interatomic or interionic) forces are still important, but the molecules have enough energy to move around, which makes the structure mobile. This means that a liquid is not definite in shape but rather conforms to the shape of its container. Its volume is usually greater than that of its corresponding solid (water is a well-known exception to this rule). The highest temperature at which a particular liquid can exist is called its critical temperature.

A liquid can be converted to a gas through heating at constant pressure to the substance’s boiling point or through reduction of pressure at constant temperature. This process of a liquid changing to a gas is called evaporation.

Gases

Gas molecules have either very weak bonds or no bonds at all, so they can move freely and quickly. Because of this, not only will a gas conform to the shape of its container, it will also expand to completely fill the container. Gas molecules have enough kinetic energy that the effect of intermolecular forces is small (or zero, for an ideal gas), and they are spaced very far apart from each other; the typical distance between neighboring molecules is much greater than the size of the molecules themselves.

A gas at a temperature below its critical temperature can also be called a vapor. A vapor can be liquefied through compression without cooling. It can also exist in equilibrium with a liquid (or solid), in which case the gas pressure equals the vapor pressure of the liquid (or solid).

A supercritical fluid (SCF) is a gas whose temperature and pressure are greater than the critical temperature and critical pressure. In this state, the distinction between liquid and gas disappears. A supercritical fluid has the physical properties of a gas, but its high density lends it the properties of a solvent in some cases. This can be useful in several applications. For example, supercritical carbon dioxide is used to extract caffeine in the manufacturing of decaffeinated coffee.

Phase Changes –What does a phase change look like at the molecular level? This video takes a look at the molecular structure of solids, liquids, and gases and examines how the kinetic energy of the particles changes. The video also discusses melting, vaporization, condensation, and freezing.

What are pathogen ?

pathogens are the biological agent that can cause a disease in another organism upon infecting and causes infectious diseases. ‘Pathogen’ is a or disease-causing organisms such as bacteria, viruses, fungi, protozoans and worms.

There are different types of pathogens such as Class 1 pathogen in which the species is not associated with infectious disease. Class 2 are the pathogen species cause disease in humans but not serious and the the preventive methods, treatments are available.

Class 3 pathogens include the species cause serious diseases in humans, but necessary prophylaxis and treatment are available; Class 4 pathogens include the species cause serious human disease and disseminate in the human population with  no adequate prophylaxis or therapy exists.

The organisms that belong to the Prokaryotic domain of life and it comes in three different shapes, such as cocci, rods, and spirals are known as Eubacteria.

What do you mean by the Prokaryotic domain?

The prokaryotic domain may be characterized as the kingdom of Prokaryotes is significantly made up of two domains namely, Archaea and Bacteria. These eubacteria are classified under the domain of bacteria which is represented by the relation based on the DNA experimental approach.

According to the context of this question, there are mainly three types of eubacteria commonly found. They are round (coccus), rod-like (bacillus), comma-shaped (vibrio), or spiral. All these types of different body plans, structures, and functions with respect to their morphology.

Therefore, eubacterium is a type of organism that belongs to the Prokaryotic domain of life and it comes in three different shapes, such as cocci, rod, and spiral.
