Explanation:
Answer:
2.627775588 degrees Celsius (with 2 sig figs)
Explanation:
We need to use our equation q=m×s×(change in temp) and solve for our change in temperature. So divide both sides by m×s and you'll get:
Change in temp=q/(m×s) Where q= J of heat m=mass and s= specific heat
So now we just plug our numbers in:
56J/(23.6g×0.903J/g°C)= 2.627775588 and since 56 only has 2 sig figs, we round the final answer to 2.6°C
