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)

a 20.94-g sample of an unknown metal is heated to 99.4 degrees Celsius in a hot water bath until thermal equilibrium is reached. The metal is quickly transferred to 100 mL of water at 22.0 degrees Celsius contained in a styrofoam cup. The thermal equilibrium temperature of the metal plus water mixture is 24.6 degrees Celsius. What is the Specific heat capacity of the metal?
9) How much energy in Kcal is needed to take 340 g of water at 6.0 degrees Celsius to steam at 127.0 degrees Celsius? ALSO indicate this process as a heating curve on the axes below. [the specific heat of ice, water and steam are 0.47, 1.00, and 0.48 cal/g oC respectively, Also the Heat of Fusion and Heat of vaporization of water are 80, and 540 cal/g respectively] You may or may not need all of these numbers. hny...
