Answer:
The specific heat capacity of water
Step-by-step explanation:
The specific heat capacity is a constant for all substances that are used in calorimetry.
Heat Definition
Firstly, we should define heat itself. Heat is the transfer of energy. Specifically, heat is the transfer of thermal energy, usually from the surroundings into a system. So, when looking for an amount of heat, we are looking for the amount of energy. This value is most commonly given in Joules (J) or Kilojoules (KJ).
Specific Heat Capacity
The specific heat capacity of a substance is the amount of heat necessary is raise the temperature of one gram by one degree Celcius. For water, this value is 4.18 J/g ·°C. So, it takes 4.18J of heat to raise the temperature of 1 gram of water by 1 Celsius degree.
