What mass of coppef would you be able to raise from 92 C to 192 C py applying 4.100 joules of heal?
Solution:
q = m × C × ΔT
where:
q = amount of heat energy gained or lost by substance (J)
m = mass of sample (g)
C = specific heat capacity (J °C−1 g−1)
ΔT = change in temperature (°C)
q = 4100 J
m = ???
C = 0.385 J °C−1 g−1
ΔT = 192°C − 92°C = 100°C
Thus:
m = q / (C × ΔT)
m = (4100 J) / (0.385 J °C−1 g−1 × 100°C) = 106.4935 g = 106.5 g
Mass of copper = 106.5 g
Answer: 106.5 grams of copper
