<span>Answer:
I guess there is is a typo in your question both change in enthalpy and change in internal energy for the combustion are negative:
â†H = -5074 kJ
â†U = - 5084.2 kJ
Work done to surrounding in a process is given by the integral:
W = â« P dV from initial to final volume
for a constant pressure process the integral simplifies to:
W = P â™ â« dV = Pâ™â†V
Enthalpy is defined as:
H = U + Pâ™V
So the change in enthalpy and the change in internal energy are related as:
â†H = â†U + â†(Pâ™V)
for a constant pressure process:
â†H = â†U + Pâ™â†V
Hence,
â†H = â†U + W
=>
W = â†H - â†U
= -5074 kJ - (-5084.2) kJ
= 10.2 kJ</span>
Answer:
10 mph faster than car 1 is going
Explanation:
Answer:
Explanation:
When a liquid is heated, the particles are given more energy. They start to move faster and further apart. At a certain temperature, the particles break free of one another and the liquid turns to gas. This is the boiling point.
When white light is diffracted and blue color is seen is due to the absorbance of wavelength of all other color except blue.
<u>Explanation:
</u>
- The white light diffracts into rainbow colors which are the 7 colors present in form of VIBGYOR.
- VIBGYOR is the violet, Indigo, Blue, Green, Yellow, Orange and Red.
- When the blue color is seen denotes the shortest wavelength being reflected and all other being absorbed at the specified location.
