The answer is the 3rd choice
Color change, temperature change, bubbling, state change
green to blue, hot to cold, bubbles (lol), and liquid to gas
2.26%, 26.8%, 2 2/5, 2.62, 271%
Hope this helps! :D
Answer: The amount of heat needed is = 4.3kJ
Explanation:
Amount of heat H = M × C × ΔT
M= mass of benzene = 64.7g
C= specific heat capacity = 1.74J/gK
ΔT = T2-T1
Where T1 is initai temperature = 41.9C
T2 is the final temperature( boiling point of benzene) = 80.1C
H= 64.7×1.74×80.7
H= 4300J
H=4.3kJ
Therefore, the amount of heat needed is 4.3kJ
