A substance releases 2,192 J of heat, changing its temperature from 50 degrees C to 5 degrees C. The mass of the substance is 73.9 grams. What is the specific heat of the substance? Round your answer to TWO digits after the decimal point.

The specific heat capacity of the given substance is -0.66 J/g°C.

Explanation:

The heat absorbed by any substance is the product of its mass, specific heat capacity and change in temperature.

q = m × c × ΔT

m is the mass in grams

q = amount of heat released or absorbed in J

ΔT = change in temperature in °C = 5 -50 = -45°C

c = specific heat capacity in J/g°C

c =

Plugin the values, we will get,

c =

= -0.66 J/g°C
