Answer:
0.384928 J/g°C
Explanation:
The formula for Specific Heat (C)
= q/m × ∆t
Where q = Heat energy required to heat the compound (in joules)
m = mass of the compound (sample)
∆t = Change in temperature
In the question, we are given the following values.
m = 5.0g
∆t = Change in temperature = 75°C - 25°C
= 50°C
q = Heat energy = 23 cal
We have to convert to joules
One calorie is equal to 4.184 joules.
1 Cal = 4.184 joules
23 Cal =
23 × 4.184 joules
= 96.232 joules
Specific Heat (C) of copper
= 96.232 J /(5g × 50°C)
= 96.232J / 250
= 0.384928 J/g°C
Therefore, the Specific Heat of Copper is 0.384928 J/g°C
