80g of propanone was heated from 25.5 degrees Celsius to 63.4 degrees Celsius. How much energy was transferred to the propanone during heating? Specific heat of propanone is 2.13J/g
Q= m×specific heat ×(T2-T1) now subtitue values then Q= (80g) × (2.13J/g)× (63.4-25.5) K on solving above we get energy transferred to propane during heating (Q)= 6458.16 J OR Q= 6.45816KJ (Kilojoules)
