Question

150J of heat energy

are required to raise the
temperature of 100g block of metal by 5°c. What is the
specific heat capacity of the metal ?

Answer 1

Btu/(lb-°F) J/(g-°C i mean this is the correct answer

Answer 2

0.300 J/(g*C)

Step-by-step explanation:

Specific heat has a unit that describes the amount of heat (J) is required to raise a unit mass (g) by 1 degree temperature (C), It should take the form of J/(g*C) if we stick with the metric units provided in the question. Be aware that specific heat can be written in many different formats, all equivalent, but with differing measures. Examples:

(BTU/kgC)

kJ/(mole*K)

J/(g*C)

and so on. The specific heat for a material can be expressed in any of these formats. There are all equivalent, just expressed with different units.

--------------

In this problem: (150J)/[(100g)*(5C)] = 0.300 J/(g*C)

An accurate value of specific heat may be used for identification of the metal. The closest I found is Barium (0.290 J/(g*C) and Zinc (0.388 J/(g*C)
