Answer:
47.6°C is the change of temperature
Explanation:
To solve this question we must use the equation of specific heat of a material:
Q = m*ΔT*S
Where Q is heat applied = 90J
m is the mass of the substance = 15g gold
ΔT is change in temperature = Our incognite
S is specific heat of the material = 0.126J/g°C for gold
Replacing:
90J = 15g*ΔT*0.126J/g°C
90J/15g*0.126J/g°C = ΔT
ΔT = 47.6°C is the change of temperature
