Question

In the formula, which quantity is measured in units of J/g degree C?

a. c.
b. M.
c. Q.
d. DT

Answer 1

In formula:

Specific heat capacity, c is measured in J/g degree C.

From Q = mcθ

c = Q / mθ = Q is in J, m might be in grammes, g, θ is in degree C

So c can be measured in J/g degree C

Answer = Option (a)

Answer 2

Answer: The correct answer is specific heat.

Step-by-step explanation:

The expression of the specific heat in terms of heat, mass and the change in the temperature is as follows;

`c=(Q)/(m\Delta T)`

Here, c is the specific heat, Q is the heat, m is the mass and
`\Delta T` is the change in the temperature.

Specific heat: It is the heat required to raise the temperature by one degree Celsius of unit mass of the substance.

The unit of heat is joule. The unit of mass is gram. The unit of temperature is degree Celsius.

Determine the unit of the specific heat.

`c=(J)/(g\degree C)`

Therefore, the correct option is (a).
