Answer:
Explanation:
The formula for the amount heat q absorbed by a substance is
q = mcΔT
where
m = the mass of the substance
C = the specific heat capacity of the material
ΔT = the temperature change
Data:
q = 2267 J
m = 44.5 g
T₁ = 33.9 °C
T₂ = 288.3 °C
Calculations:
ΔT = (288.3 - 33.9) °C = 254.4 °C
