Question

the thermal capacity of a body of mass 100gms and specific heat 0.11caloriepergdegree celcius ?

Answer 1

Hello Dear, 

Your answer is here,

Given Mass (m) = 100 gm
                          = 0.1 kg

Thermal Capacity ( 'C) = 0.11 cal /°C
                                     = 0.11 × 4.2 J/°C
                                     = 0.462 J/°C

Using the formula,
              Thermal Capacity = Mass × Specific heat capacity
                                0.462   = 0.1 × c
                                c  =  0.462 / 0.1
                               
                               c = 4.62 J / Kg°C

Thus specific heat capacity is 4.62 J /kg°C
                  

Hope it helps.

Have a marvelous day.

Answer 2

Given :

mass= m= 100gms

Specific Heat Capacity =S= 0.11 cal/g°C

Formula to be used :
Thermal Capacity = mass X specific heat capacity for unit temperature.

Q=mS
where m is mass and
S is specific heat capacity.

Q= 0.1 x 0.11
Q=0.011cal.

1cal = 4.2 Joules 
Q= 0.011 x 4.2 Joules =0.0462 joules 

∴The Thermal capacity of body is 0.0462 joules.
