Superheat
It can be used to describe a process where refrigerant vapour is heated from its saturated condition to a condition at higher temperature.
The term superheat can also
be used to describe - or quantify - the end condition of the before-mentioned process.
. Therefore, superheat can not be deter2.7 Superheat mined from a single measurement of temperature alone - a measurement of pressure or saturation temperature is also needed.
Skis
-
The same weight is distributed on
the area of his shoe soles - which is a much smaller area than the area of the skis.

Forms energy
The transfer of heat is closely connected to the temperature (or temperature difference) that exists between two or more objects.
By itself heat is always transferred from an object with high temperature to objects with lower temperatures.

Heat and work are both forms of energy that can be transferred between objects or systems. The transfer of heat is closely connected to the temperature (or temperature difference) that exists between two or more objects.
Temperature units
The SI unit of temperature Kelvin (K) is an absolute temperature because its reference point is (0 K).
is the lowest temperature it can get.
To reduce the temperature of an object the object you want to get its heat or cold has to have more or less degrees than the second object so that it is faster and can acquire almost the same degrees.
In refrigeration systems the Celsius (°C) temperature unit is used. It is not an absolute temperature scale because its reference point which is (0 °C) is defined by the freezing point of water (equal to 273.15 K).
The property that makes iron and air different with respect to the energy required to cause a temperature rise is called the "specific heat capacity". It is the energy required to cause a temperature rise of 1 K for 1 kg of the substance. The unit of specific heat capacity is J/kg K.
Refrigeration Plant

-
The job of a refrigeration plant is to cool articles or substances down to, and maintain them at a temperature lower than the ambient temperature. Refrigeration can be defined as a process that removes heat.

Temperature is a very central property in refrigeration. Almost all refrigeration systems have the purpose of reducing the temperature of an object
