Question

An unknown substance with a mass of 25 grams releases 550 joules of energy when undergoing a temperature increase of 10 degrees Celsius. What is the specific heat of that substance? Show your work

Answer 1

Answer:

Explanation:

We Know That,

Q = m×C×∆T

Consider the substance as a solid so Cp = Cv

Given,. Q= 550 Joules, ∆T = 10℃, m= 25g

So, 550 = 25 × C × 10

C= 55/25

C= 2.2 Joule per gram Kelvin (J/GK)

Here Temperature is given in difference so Kelvin or ℃ can be used.
