Every substance has a specific value of heat required to change the temperature of 1 gram of the substance by 1 degree celsius. specific heat is found by using the equation q=mcδt, where q represents heat in joules, m represents mass in grams, δt is the change in temperature in celsius, and c is the coefficient constant for a substance. find the units for the coefficient c.
a)
c=j·g·°c
b)
c=j·g/°c
c)
c=j/g·°c
d)
c=g·°c/j

The correct answer to the question is : C)

EXPLANATION:

The amount of heat required to raise the temperature of one gram of substance through one degree celsius is known as the specific heat capacity.

The equation given is Q = mcΔt

Here, Q is the heat given to the substance.

          m is the mass of the substance.

           c is the specific heat capacity.

          Δt is the change in temperature.

We are asked to calculate the unit of c.

The unit of c is calculated as -

                                             c =

                                                =

                                                =

Hence, the unit of c is
