Category:Definitions/Calorie
This category contains definitions related to Calorie.
The calorie is a CGS unit of heat energy.
It was originally defined as equal to the energy required to raise the temperature of $1$ gram of water by $1 \cels$.
However, it is noted that this energy depends upon the initial temperature of the water itself.
Hence there are a number of different definitions for the calorie:
$4 \cels$ Calorie
The $4 \cels$ calorie is a CGS unit of heat energy.
It is defined as equal to the energy required to raise the temperature of $1$ gram of water from $3 \cdotp 5 \cels$ to $4 \cdotp 5 \cels$ at standard atmospheric pressure.

$15 \cels$ Calorie
The $15 \cels$ calorie is a CGS unit of heat energy.
It is defined as equal to the energy required to raise the temperature of $1$ gram of water from $14 \cdotp 5 \cels$ to $15 \cdotp 5 \cels$ at standard atmospheric pressure.

$20 \cels$ Calorie
The $20 \cels$ calorie is a CGS unit of heat energy.
It is defined as equal to the energy required to raise the temperature of $1$ gram of water from $19 \cdotp 5 \cels$ to $20 \cdotp 5 \cels$ at standard atmospheric pressure.

Mean Calorie
The mean calorie is a CGS unit of heat energy.
It is defined as equal to $\dfrac 1 {100}$ the energy required to raise the temperature of $1$ gram of water from $0 \cels$ to $100 \cels$ at standard atmospheric pressure.
