Condensation occurs when the molecules of a gas cool. The molecules lose energy and slow down as they lose heat. They approach other gas molecules and combine to form a liquid.On the other hand, the process of a liquid becoming a gas is called vapourization.Some examples of condensation reactions are listed below: When water droplets …
Definitions
Distillation is the separation of a mixture of liquids based on differences in their boiling points (or volatility). Water can be extracted from a salt solution using this method. Because the boiling point of the dissolved solute (salt) is greater than that of the solvent (water). Solvent vapor evaporates from the solution as it is …
The amount of heat that must be added (or removed) from a unit mass of a substance to change its temperature by one degree Celsius is referred to as “specific heat.” It is a powerful property. To put it simply, equal masses of different substances require varying amounts of heat to raise them through the …
Energy definition: Energy is defined as the ability to do work is called energy and work is moving something against a force, for instance, gravity.Simply put, energy is the ability to do work. When we work on something, some of our energy is transferred to it. When energy is transferred, the object being worked on …
Potential energy definition: Potential energy is the energy that an object has due to its position. If the object is lifted straight up at a steady speed, then the force (F) required to lift it to the height (h) is equal to its weight (mg).In other words, when an object is lifted to a higher elevation, …
Critical thinking definition: Critical thinking is defined as the process of actively and skillfully conceptualizing, applying, analyzing, synthesizing, and evaluating information gathered from or generated by observation, experience, reflection, reasoning, or communication.Someone who can think critically and clearly about what they should or should not believe is capable of critical thinking. They are capable of …
Definition of work in physics: The work done on a system by a constant force is the product of the force component in the direction of motion multiplied by the distance over which the force acts. For one-way motion in one dimension, the work formula is given as W = Fd cos θ, where W is work, F is the magnitude of the force …
Force definition: Force is an external agent capable of changing the state of rest or state of motion of a particular body. It can move or tend to move an object or it can stop or tend to stop an object. It is a vector quantity. Some examples are listed below: How does Force work? …
Filtration is a process that uses a medium called a filter to separate solid particles from liquids or gases. Air filters, water filters, oil filters, and quarium filters are examples of the filtration processes. A filter is a membrane that separates suspended solids from liquids by passing them through its pores. In simple terms, the …
Pressure definition: The force acting normally per unit area on the surface of a body is called Pressure. In other words, the pressure is force distributed over an area. Examples of pressure include air pressure in car tire support, sucking a drink through a straw, and flying aircraft. Pressure is a scalar quantity and Its …
Amino acids definition: Amino acids are organic compounds that contain both amino and carboxylic groups. Amino acids are the building blocks of proteins. Proteins are complex macromolecules composed of amino acids and found in all living cells. We are aware of about 500 naturally occurring amino acids. Amino acids are the monomers that form proteins …
Relative density definition: Relative density, also known as specific gravity, is the ratio of a substance’s density to the density of a standard substance. The standard of comparison for solids and liquids is water at 4 °C (39.2 °F), which has a density of 1.0 kg per liter (62.4 pounds per cubic foot). In simple …
In mathematics, composite numbers are whole numbers with more than two factors. Non-prime whole numbers are composite numbers because they are divisible by more than two numbers. Some key points about composite numbers are listed below: Composite Numbers Definition A composite number is a positive integer that can be produced by multiplying two smaller positive …
Circum of circle definition: The circumference of a circle is the circle’s perimeter. It is the total length of the circle’s boundary. The circle’s circumference is the product of the constant π and the circle’s diameter. What is a Circle? A circle is a planar figure bounded by one curved line and defined by the …
An emulsion is a mixture of two or more unmixable and unblendable liquids. It is a term that is used in chemistry. It means that the dispersed phase and the dispersion medium in an emulsion are both liquids. Some examples of emulsion are listed below: Oil in water: When oil and water are shaken together, …
