Answer:
<h3>
Which of the following increases with the increase in the temperature in case of a liquid?</h3><h2>
<em>Va</em><em>pour</em><em> </em><em> </em><em>Pressure</em><em> </em></h2>
Explanation:
When a closed container contains liquid, higher the temperature, higher the evaporation the evaporation will be.
So Vapour Pressure should be the correct answer.
Friction. Imagine rubbing your hand against a carpet and how it gets hot even though you are pushing it afar. That is friction.
5.7% KCl is 94.3 % water.
Therefore, for 1000 g of water the mass of KCl will be (1000× 5.7)/94.3 = 60.445 grams.
1 mole of KCl is equal to 74.55 g,
therefore, 60.445 g will be 60.445/74.55 = 0.8108 mole of KCl
Hence, 0.8108 moles of KCl should release twice that number of moles 1.6216 moles ions.
Having 1.6216 moles of KCl ions dissolved in 1000g of water, gives us 1.6216 molar if solution.
Using the freezing point depression constant of water.
dT = Kf (molarity)
dT = (1.86 C/ molar) (1.6216 m)
dT = 3.016 C drop in freezing point
Therefore, it should freeze at - 3.016 Celsius
In order to compress a gas, high pressure should be met. <span>There are three major groups of compressed gases stored in cylinders: liquefied, non-liquefied and dissolved gases. In each case, the pressure of the gas in the cylinder are high. Hope this helps.</span>
