Question

1. A piece of copper 125g has a heat capacity of 19687.6J .Also it is heated from 150 to 2500°C heat. Find out the specific heat?
Please answer in brief......​

Answer 1

Answer:

245 kg is the answer of this question

Answer 2

Answer:

The specific heat capacity is 1.575 J/g°C.

Explanation:

Given:

Mass (m) = 125g

Heat capacity (Q) = 19687.6J

T₁ = 150°C

T₂ = 250°C

To find:

Specific heat capacity (c)

Formula:

$c = \frac{Q}{m*dT}$

Solution:

The specific heat capacity is defined as the amount of heat required to change the temperature of the unit mass of a given substance by 1°C.

dT = T₂ - T₁

dT = 250 - 150

dT = 100°C

Substituting the given values, we get

$c = \frac{Q}{m*dT}$

$c = \frac{19687.6}{125*100}$

$c = \frac{19687.6}{12500}$

c = 1.575J/g°C

Therefore, the specific heat of 125g copper is 1.575J/g°C.
