The SI unit of specific heat capacity is
ACalorie per kilogram per kelvin
BJ per gram per degree Fahrenheit
CJ per kg per degree Celsius
DNewton per kilogram per kelvin
Answer & Solution
Correct answer: C. J per kg per degree Celsius
1. c = Q / (m * delta T) gives the unit.
2. Q in joules, m in kilograms, delta T in degrees Celsius.
3. Hence c has units J / (kg * deg C).
4. So option A is correct.
