Which units express specific heat capacity?
J/°C, J/K, cal/°C cal/K J
/(gi°C), J/(giK), cal/(gi°C), cal/(giK)
J, cal
°C, K
Answer : The correct option is \(\frac{J}{g^oC},\frac{J}{gK},\frac{cal}{g^oC},\frac{cal}{gK}\).
Explanation :
Specific heat capacity : It is defined as the amount of heat required to raise the temperature of one gram of substance by one degree Celsius.
Formula used :
\(q=mc\Delta T\\c=\frac{q}{m\Delta T}\)
where,
q = heat required
m = Mass
c = specific heat capacity
\(\Delta T\) = change in temperature
The unit of heat are expressed in terms of Joules, calories.
The unit of temperature are expressed in terms of degree Celsius, kelvin.
It is expressed as \(\frac{J}{g^oC},\frac{J}{gK},\frac{cal}{g^oC},\frac{cal}{gK}\).
The units to express specific heat capacity are cal/K, cal/\(\rm ^\circ C\), J/K, and J/\(\rm ^\circ C\). Thus the correct option is A.
Specific heat can be defined as the amount of heat required to raise the temperature of 1 gram of a substance by 1 degree celsius.
The expression for specific heat has been,
heat = mass \(\times\) specific heat capacity \(\times\) change in temperature
Calorie or Joule = g \(\times\) specific heat \(\times\) K or \(\rm ^\circ C\)
Specific heat will be:
Thus, the units to express specific heat capacity are cal/K, cal/\(\rm ^\circ C\), J/K, and J/\(\rm ^\circ C\). Thus the correct option is A.
