thermodynamics - Why is a degree Celsius exactly the same as a Kelvin? - Physics Stack Exchange
The size of the degree Celsius and the kelvin are identical. The difference is that the zero point in the kelvin scale is set at absolute zero, and. Lord Kelvin, working in Scotland, developed the Kelvin scale in The relationship between degrees Fahrenheit and degrees Celsius is. In Celsius scale, the melting point of ice is 0Â°C and the boiling point of water is Â°C.. While, in Kelvin scale, the melting point of ice is K and the boiling.
The idea for the Kelvin scale was sparked by a discovery in the s of a relationship between the volume and the temperature of a gas. Scientists theorized that the volume of a gas should become zero at a temperature of minus The Kelvin scale compared to Celsius and Fahrenheit.
Designua Shutterstock Absolute zero InKelvin used this as a basis for an absolute temperature scale. He defined "absolute" as the temperature at which molecules would stop moving, or "infinite cold.
Absolute zero cannot technically be achieved. However, scientists have been able to lower the temperature of matter to just a fraction of a Kelvin above absolute zero through techniques such slowing down particles using lasers.

The Kelvin scale was also influenced by the Carnot engine, a theory that examines the relationship between pressure, work and temperature.
It is one of the fundamentals of physics and thermodynamics and is a measure of the efficiency of an engine. Kelvin was a talented mathemetician, which played a role in some of his other inventions, including a device that led to the success of the telegraph cable and many nautical instruments. His research into the nature of heat helped him form the second law of thermodynamics, which states that heat will not flow from a colder body to a hotter body.
Kelvin's documentation of the law says that some of the heat from a high-temperature energy source will be downgraded to low-quality energy.

Uses of the Kelvin scale The Kelvin scale is popular in scientific applications because of the lack of negative numbers. This scale is convenient for recording the very low temperatures of liquid helium and liquid nitrogen, for example.
Later, the number of increments shown on a thermometer increased as measurements became more precise.
State the relationship between degrees Celsius and kelvins
It is based on the melting and boiling points of water under normal atmospheric conditions. The current scale is an inverted form of the original scale, which was divided into increments. Because of these divisions, the Celsius scale is also called the centigrade scale. His scale uses molecular energy to define the extremes of hot and cold.
Absolute zero, or 0 K, corresponds to the point at which molecular energy is at a minimum. The Kelvin scale is preferred in scientific work, although the Celsius scale is also commonly used.
Converting between Scales The kelvin is the same size as the Celsius degree, so measurements are easily converted from one to the other. The Kelvin and Celsius scales are related as follows: The relationship between degrees Fahrenheit and degrees Celsius is as follows:
