Question

Calculate the specific heat capacity of the unknown metal given the

following information; the mass of the metal is 225 g, the temperature
raises by 13C and the energy absorbed was 1363 joules.

A. 0.466 j/gC
B.1.02j/gC
C.0.96 j/gC
D.2.14 j/gC

Answer 1

Answer: The specific heat capacity of the unknown metal given is
`0.466 J/g^(o)C`.

Step-by-step explanation:

Given: Mass = 225 g

Change in temperature =
`13^(o)C`

Heat energy = 1363 J

The formula used to calculate specific heat is as follows.

`q = m * C * \Delta T`

where,

q = heat energy

m = mass of substance

C = specific heat

`\Delta T` = change in temperature

Substitute the values into above formula as follows.

`q = m * C * \Delta T\\1363 J = 225 g * C * 13^(o)C\\C = (1363 J)/(225 g * 13^(o)C)\\= 0.466 J/g^(o)C`

Thus, we can conclude that the specific heat capacity of the unknown metal given is
`0.466 J/g^(o)C`.
