Answer:
20.9 J
Explanation:
Given Values
Mass = 0.5g
Change of temperature = 20°C ---- 30°C
Specific Heat = 4.18 J/g °C
Heat = ?
By usung the formula for heat energy, where
q = mcΔT
m = mass
c = specific heat
ΔT = change of temperature
q = heat energy
q = (0.5 g)(4.18 J/g °C)(30°C - 20°C)
q = (0.5 g)(4.18 J/g °C)(10°C)
q = 20.9 J
