What is the specific heat of an unknown substance if 2000 J of energy are required to raise the temperature of 4 grams of the substance 5 degrees Celsius
🔄 Click to see definition
Definition1/13
q = m x C x Δt, where q is amt of heat gained or lost, C is specific heat capacity, and Δt is change in temperature.
Known:
q = 2000J
m = 4g
Δt = 5oC
Equation:
C = q/mΔt
Solution:
C = 2000J/4g5oC = 2000J/20goC = 100J/goC
