What units are appropriate to express specific heat?
Answer:
Specific heat is a physical property that describes how much energy is needed to change the temperature of a substance by a certain amount. Specific heat is typically expressed in units of energy per unit mass per degree Celsius (or Kelvin). The most commonly used units to express specific heat are Joules per gram per degree Celsius (J/g°C) or Joules per gram per Kelvin (J/gK). Another frequently used unit is calories per gram per degree Celsius (cal/g°C) or calories per gram per Kelvin (cal/gK). In the International System of Units (SI), the unit of energy is the Joule, but the calorie is also widely used in specific heat calculations.
