Specific heat of the metal is the heat amount required to increase the temperature. The specific heat (c) of metal is 0.73 J/g/°C.
What is specific heat?
Specific heat is the heat that is utilized by a gram of a substance to increase the temperature by a degree.
Given,
Mass (m) = 22.0 gm
Heat (H) = 713 J
T1 = 28.3 °C
T2 = 72.8 °C
Specific heat is calculated as:
Δ H = m c (T2 - T1)
713 = 22 × c × (72.8 - 28.3)
c = 713 ÷ (22 × 44.5)
= 0.728 J/g/°C
Therefore, 0.73 J/g/°C is the specific heat of the metal.
