Based on the question, it is evident that this question rests on the premise of Charle's Law, which essentially states that temperature is proportional to volume once pressure and mass remain constant.
Thus by Charle's Equation:
Since the initial volume = 2.2 L; the initial temperature = 20 C; and the final volume = 2.6 L,
then V₁ = 2.2 L; T₁ = 20 C; V₂ = 2.6 L and what we would be
finding is T₂ (the final/new temperature)
Now,
⇒
⇒
∴ the new temperature is ≈ 23.6 °C
Answer: Option (d) is the correct answer.
Explanation:
Convection is defined as the process in which when heat is supplied to a fluid (liquid or gas) then denser substance (cooler) will sink at the bottom whereas less dense substance (hotter) will rise towards the top.
This intermixing of fluids leads to the generation of convection currents. This macroscopic motion of fluid particles is responsible for convection.
Also, contribution due to the random molecular motion reduces as the flow progresses in perpendicular direction from the surface. Heat transfer is dominated by random molecular motion near the surface where fluid velocity is low.
Thus, we can conclude that out of the given options wrong statement is heat transfer occurs solely due to random molecular motion at the interface between fluid and surface where the fluid velocity is zero.
Answer:
<h3>The answer is 2.65 mL</h3>
Explanation:
The volume of a substance when given the density and mass can be found by using the formula
From the question
mass = 2 g
density = 0.756 g/mL
So we have
We have the final answer as
<h3>2.65 mL</h3>
Hope this helps you
Answer:
The C-O stretch of phenol
Explanation:
Electron delocalization causes the of the phenol to have partial double bond character, whereas the  of the cyclohexanol is a pure single bond. Again, we know as the bond order or bond strength increases the absorption occurs at larger wave number. So, the  stretch of the phenol occurs at larger wave number.
