Answer: D. Increase the amount of travel done by bike.
Explanation:
Environment protection has become a concerned issue for the human society because of the fact that certain human activities are deteriorating the quality of air, water, and soil by liberating wastes into the environment.
Among the options given, D. Increase the amount of travel done by bike. is the correct option. This is due to the fact that use of bike instead of using automobile like car will prevent the large amount of emission of harmful gases which are capable of polluting the air, water and soil can be restricted.
The total energy required for this conversion is equivalent to the sum of the energies that are used. There are three steps:
1) Heating of liquid acetone
This used 628 J
2) Evaporation of acetone
This used 15.6 kJ or 15,600 J
3) Heating of acetone vapors
This used 712 J
Adding these quantities,
Total energy = 628 + 15,600 + 712
The total energy required was <span>16940 Joules of 16.94 kJ</span>
<span>When the aqueous solution is heated to 85âC, the gas entrapped in the aqueous solution is released since the vapour pressure of the particular entrapped gas is more than the solution. The solid saturated in the aqueous solution returns back to its original form once the aqueous solution evaporates. A good example is that of the salt left behind after heating a brine solution to evaporate.</span>
The precision of a calculated answer is limited by the least precise measurements used in the calculation.
Hope this helps :)
