alcohol same with the soap
Answer:
5.167 kJ
Explanation:
We have to divide the heating process into two steps: one for the heating process of liquid water (1) and the other for the phase transition from liquid water to steam at 100°C (2)
1 - heating from 52.1°C to 100°C:
heat(1) = m x Cp x ΔT = 2.1 g x 4.184 J/g°C x (100°C-52.1°C) = 420.9 J
2 - vaporization at 100°C:
heat(2) = m x ΔHv = 2.1 g x 2260 J/g = 4746 J
Finally, we add the heat values of the steps:
heat required = heat(1) + heat(2) = 420.9 J + 4746 J = 5166.9 J
Since 1 kJ= 1000 J, we convert from J to kJ:
5166.9 J x 1 kJ/1000 J = 5.1669 kJ ≅ 5.167 kJ
The best answer would be HUMANS.
This is because organic compounds are essentially carbon based compounds and the human body is made up of many such compounds such as the protein that makes up skin, hair, nails, hormones and enzymes; gylcoproteins that are essential for cell membrane; fat found in skin and other tissues.
During combustion, chemical energy stored in fossil fuels is converted into KINETIC energy.
It’s b for sure that’s the answer
