Find c for 455 grams of metal that gives off 1638 j while changing temperature by 6c.

c = 0.6 J/g°C

Explanation:

Heat is given by the formula;

Heat = mass× specific heat capacity × change in temperature

Mass = 455 g

Heat = 1638 J

ΔT = 6 °C

Therefore;

1638 J = 455 g× c × 6

c = 1638/(455×6)

c = 0.6 J/g°C
