Answer:

The responses to the questions are:

a. The entropy of sublimation for CO2 is 134.07 J/Kmol.

b. The entropy for the universe in this reversible scenario is 376 J/K.

Explanation:

Entropy of sublimation refers to the change in entropy that occurs when one mole of a solid transitions to vapor at its sublimation point.

a. The mass of solid CO₂ is noted as 389 g.

The molar mass of CO₂ is 44.01 g/mol.

The number of moles of CO₂ in the sculpture is calculated as: Mass/(Molar mass)

= (389 g)/(44.01 g/mol) = 8.84 moles.

The entropy of sublimation is expressed as

ΔS = - S =

Where:

ΔH  = 26.1 KJ/mol.

T = Temperature = –78.5°C = ‪194.65‬ K.

Consequently, the energy required for the 389 g of dry ice to sublime is: 26.1 KJ/mol × 8.84 moles = 230.695 KJ.

Subsequently, the entropy of sublimation is calculated as ΔS =

= 1.185 KJ/K

= 1185 J/K = 1185/8.84 J/Kmol = 134.07 J/Kmol.

b. The universe’s entropy can be computed as:

ΔS = + ΔS

If the heat absorbed by the system equals the heat released by the surroundings, then:

ΔS =  

                =1.185 KJ/K - = 1.185 KJ/K - 0.809 KJ/K = 0.376 KJ/K

= 376 J/K.

Response:  The updated temperature stands at 10643 K

Clarification:

The combined gas law integrates Boyle's law, Charles's law, and Gay-Lussac's law.

The equation for this law is given by:

where,

= initial gas pressure = 750.0 mm Hg = 0.98 atm   (760mmHg=1atm)

= final gas pressure = 3.50 atm

= initial gas volume = 2.00 L

= final gas volume = 20.0 L

= initial gas temperature =

= final gas temperature =?

Now substituting all the stated values into the equation, we obtain:

Thus, the new temperature results in 10643 K

Consequently, she feels very anxious because she has 345600 seconds to wait. Explanation: 60 seconds make up 1 minute, and 60 minutes constitute an hour. Each hour has 3600 seconds (60*60) and 24 hours make up a day. Hence, 3600 seconds multiplied by 24 hours results in 1 day equating to 86400 seconds—therefore, over four days, we have 86400 * 4 equating to 345600.
