The arrow that represents the transition in which dew is formed would be arrow 4.
<h3>How is dew formed?</h3>
Dew is formed by condensation. Condensation, in itself, involves a transition from a gas phase to a liquid phase.
From the diagram, the arrow that represents a transition from gas to liquid is arrow 4.
Thus, the arrow that represents the transition that leads to the formation of dew would be arrow 4.

pH=pKa+log([A-/HA])
25% deprotonated tells us that A- is .25 and that the rest (75% is protonated) thats .75.
4 = pKa + log \frac{.25}{.75}
4 - log \frac{.25}{.75} = pKa
4.48=pKa
90 elements occur naturally on earth.
Answer : The specific heat of metal is
.
Explanation :
In this problem we assumed that heat given by the hot body is equal to the heat taken by the cold body.


where,
= specific heat of metal = ?
= specific heat of water = 
= mass of metal = 129.00 g
= mass of water = 45.00 g
= final temperature = 
= initial temperature of metal = 
= initial temperature of water = 
Now put all the given values in the above formula, we get


Therefore, the specific heat of metal is
.
