11. (a) A 4.50 mol sample of an ideal gas is compressed irreversibly and isothermally at 96.22 K from an initial volume of 20.00 L in two steps: Step #1: Pext = 5.00 bar, Step #2: Pexe =
20.00 bar. Determine the value of the total work and heat involved.
(b) [2 marks] Describe in words what happens to the total amount of work if the compression
occurs in three steps.
(0) [2 marks] Assuming the process could be done in one or multiple steps and the process could
be reversible or irreversible, determine the minimum and maximum amount of work that could be
done to complete the compression.

- both b and d.

-since b and d are the closest coastlines then that makes it the most affected.

< 3

so here we go

atomic mass

239 + 1 = y + 134 + 3 combine like terms

240 = y + 137             subtract 137 from both terms

240 - 137 = y

103 = y

atomic number

94 = z +54 + 0

94 = z + 54               subtract 54 from both sides.

40 = z

answer

answer : one can design an experiment using a liquid and an additive that can be added to the liquid and observe the chemical changes in the reaction species.

one would need a beaker which is filled with a known amount of the liquid in which thermometer is placed to measure the temperature changes; after addition of the additive to the liquid solution one can note down the temperature change and find whether the reaction is endothermic or exothermic in nature. by subtracting the initial temperature value with the final temperature one can find the temperature changes.

various combinations of liquid and additive can be used. liquid in this case can be a known quantity of water and additives can be epsom salt or without epsom salt the experiment can be conducted to notice the changes. water and ice, hydrogen peroxide and dry yeast, vinegar and baking soda,etc.
