Answer: 5,242 J
Explanation:
Step by step:
The formula for this is Q=mcΔT
Find out your values and then plug-and-play.
Q= unknown (energy amt we need to find out)
m= 167g
c= 2.093 J/go°C
ΔT= -20.0° + 15° would give you -5.0°
Plug into the equation for Q=(167g)(2.093 J/g°C)(15°C).
Solve and you get 5,242 J.
hope this helps!!
