Answer:
directly proportional to one another
Explanation:
Volatility refers to how quickly a substance changes from liquid to gas.
If a substance has a high vapour pressure, the substance is highly volatile. Similarly, if a substance has a low vapour pressure, then the substance is much less volatile.
This implies that volatility and vapour pressure gives a direct proportionality.
The concentration of OH⁻ is first converted to pOH bu using followinf formula,
pOH = -log [OH⁻]
Putting value,
pOH = -log (0.006)
pOH = 2.221
As we know,
pH + pOH = 14
Solving for pH,
pH = 14 - pOH
Putting value of pOH,
pH = 14 - 2.221
pH = 11.779
Result:
Option-1 is the correct answer.
When ice is warmed above freezing, its dispersed particles absorb energy and begin to move faster.
