Answer: 1.55 Jg°C
Explanation:
The quantity of Heat Energy (Q) required to heat a substance depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)
Thus, Q = MCΦ
Since,
Q = 943 joules
Mass of oil = 10g
C = ? (let unknown value be Z)
Φ = (Final temperature - Initial temperature)
= 89°C - 28°C = 61°C
Then, Q = MCΦ
943 J = 10g x Z x 61°C
943J = 610g°C x Z
Z = (943J / 610g°C)
Z = 1.55 Jg°C
Thus, the specific heat of the oil is 1.55 Jg°C
