A critical point, also known as a critical state, occurs under substance-specific sets of conditions, (such as specific conditions of temperature, pressure or composition), and under these substance-specific conditions no phase boundaries exist. The state of the substance is specified by some number of state variables, like gases are described by pressure, temperature and volume. This table lists critical temperatures, critical pressures, and corresponding critical molar volumes, for various substances and these are often used in predictive state equations for real gases.
The Specific Heat calculator computes the specific heat of an item based on the heat energy applied, the mass of the object and the change in temperature. Specific Heat is the heat transfer capacity per unit mass of a material.
This equation computes the temperature component of the Fatigue Strength for a material.

Humidity is defined as the amount of water vapor in the air.
This calculator provides functions to convert temperatures to/from Fahrenheit, Celsius, Kelvin and Rankine.
Planck Temperature, `T_P` is the unit of temperature in the system of natural units known as Planck units. It serves as the defining unit of the Planck temperature scale. In this scale the magnitude of the Planck temperature (denoted `T_P`) is equal to 1, while that of absolute zero is 0. Other temperatures can be converted to Planck temperature units. This constant returns the Planck temperature in degrees Kelvin by default.

Critical Point for temperature occurs at specific conditions where no phase boundary exists. There are multiple critical points, including liquid-vapor and liquid-liquid critical points.
The efficiency of the engine can also be referred to as Carnot Efficiency, is the fraction of the in-going heat energy that is converted to available work.For example the efficiency of a Carnot engine having a hot reservoir of boiling water and a cold reservoir ice cold water will be 1-(273/373)=0.27, just over a quarter of the heat energy is transformed into useful work.
