This has all of the charges above the columns. Hopefully it helps!
Answer:
The total heat required is 4088.6 J
Explanation:
We have three processes which involve heat absorption. We have to calculate the heat of each process and then to calculate the total heat.
1- liquid ethanol is heated from 25ºC (298 K) to the boiling point 78.5ºc (351.5 K). We use specifi heat of liquid ethanol to calculate the heat absorbed in this part:
H1= m x Sh x ΔT
H1= m x Sh x (Tfinal - Tinitial)
H1= 3.95 g x 2.45 J/g.K x (351.5 K -298 K)
H1= 517.7 JExplanation:
Answer:
If the material is opaque, light is reflected or absorbed. If the material is transparent, all light is transmitted. If the material is translucent, the light is scattered. The higher the frequency, the more energy the light waves have. The lower the frequency, the less energy the light waves have.
Explanation:
I'm literally learning about it right now and I got it right.
