The boiling point<span> is the temperature at which the vapor pressure of the liquid equals the surrounding pressure. At this temperature, liquid gets converted into vapour phase.
</span>
Now, if one goes to higher heights, i.e. mountains, pressure decreases. Since, pressure decreases the boiling point also decreases. Hence, if heating rate is same, the time needed to reach the boiling point will decrease.
Answer:
Ba,Sr,Ca,Be
Explanation:
as atomic size increases ionisation potential decreases
Alkaline earth metals
group 2 (IIA)
Answer:
375 K
Explanation:
Using the experssion shown below as:
At vaporization point, the liquid and the gaseous phase is in the equilibrium.
Thus,
So,
Given that:
Also, 1 kJ = 10³ J
So,
So, temperature is :
<u>T= 375 K</u>
The best and most correct answer among the choices provided by your question is the second choice or letter B.
<span>Regarding the second electron affinity for an oxygen, i. e., the electron affinity for O-, it is much larger and negative.</span>
