Final answer:
The SI units of specific heat are J/(kg·K) or J/(kg·°C), representing the amount of heat energy required to raise the temperature of one kilogram of a substance by one Kelvin or one degree Celsius.
Step-by-step explanation:
The SI units of specific heat are J/(kg·K), which stands for joules per kilogram per Kelvin. This unit represents the amount of heat energy required to raise the temperature of one kilogram of a substance by one Kelvin. It is important to note that specific heat can also be expressed in J/(kg·°C) since a temperature change in Kelvin is the same as a temperature change in degrees Celsius, but the SI unit is J/(kg·K).
