The heat needed to raise the temperature is 1.49kJ.
The amount of energy needed to raise the temperature of one gram of a substance by one degree Celsius.
By the formula
Q = m × c × ∆T
Where, Q = amount of heat (joules)
m = mass (g) 236 gram
c = specific heat of silver, 0.24 J/g°C
∆T = change in temperature (°C) 8.5 to 34.9
∆T = T2 - T1 = 34.9 - 8.5 = 26.4°C
Putting the value in the equation
Q = 236 × 0.24 × 26.4
Q = 1,495.3 Joules
Thus, heat needed to raise the temperature is 1.49kJ.
