Which of the following is the SI unit for heat?
A
joule
B
kelvin
C
watt
D
calorie
Verified step by step guidance1
Understand that heat is a form of energy transfer due to temperature difference between systems.
Recall that the SI unit for energy, and therefore for heat, is the joule, symbolized as J.
Note that kelvin (K) is the SI unit for temperature, not heat.
Recognize that watt (W) is the SI unit for power, which is energy per unit time, not heat itself.
Know that calorie is a unit of heat but it is not an SI unit; it is commonly used in some contexts but the SI unit remains the joule.
