Question

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 1

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 $\frac{J}{g^oC},\frac{J}{gK},\frac{cal}{g^oC},\frac{cal}{gK}$.

Answer 2

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:

• cal/k
• cal/$\rm ^\circ C$
• J/$\rm ^\circ C$
• J/K

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.
