Answer:
1.571 J/g°C
Explanation:
Using Q = mc∆T
Where;
Q = amount of heat in Joules
m = mass of substance (grams)
c = specific heat capacity
∆T = change in temperature (°C)
According to the question;
m = 140g, Q = 440J, ∆T = 22°C - 20°C = 2°C
Using Q = mc∆T
c = Q/m∆T
c = 440/ 140 × 2
c = 440/280
c = 1.571 J/g°C
