If +ΔS means an increase in entropy, or disorder, then a solid subliming into a gas would be an increase in disorder.
Answer:
31°C
Explanation:
Using the ratio, we can find the temperature of the gas at 705mm.
725mm : 32°C
705mm : <em>x</em>
[ <em>x</em> is the temperature we have to find ]
Cross multiply the ratios.
725<em>x</em> = 705 × 32
725<em>x</em> = 22560
<em> x</em> = 
= <u>31°C</u>
Answer:
0.17M
Explanation:
5kg of water contains 5 liters as the density of water is 1000 
Therefore one liter of water contains 31/5=6.2g of HCl
Molality of the solution = 6.2/36.46 =0.17M
