What are the SI units for specific heat capacity? A. J B. J/ºC C. J/gºC D. J/g
1 answer:
Answer:
C. J/gºC
Explanation:
The specific heat capacity of a substance is defined as the amount of heat energy that must be supplied to 1 kg of a substance in order to increase the temperature of that substance by 1 ºC.
Mathematically, it is calculated as:
where
Q is the amount of heat energy supplied to the substance
m is the mass of the substance
is the increase in temperature of the substance
We know that:
Q (energy) is measured in Joules (J)
m (mass) is measured in grams (g)
(temperature) is measured in Celsius degrees (ºC)
Therefore, the SI units of specific heat capacity are
