Answer:
0.385 J/g°C
Explanation:
Using the following formula, the specific heat of an elemental substance can be calculated:
Q = m × c × ∆T
Where;
Q = quantity of heat (J)
m = mass (g)
c = specific heat capacity (J/g°C)
∆T = change in temperature (°C)
Based on the given information, Q = 1375J, m = 50g, initial temperature = 22.8°C, final temperature = 94.2°C, c =?
Q = m × c × ∆T
1375 = 50 × c × (94.2 - 22.8°C)
1375 = 50 × c × 71.4
1375 = 3570c
c = 1375/3570
c = 0.3851
c = 0.385 J/g°C
