Chapter 5: Problem 17

(a) What is meant by the term system in thermodynamics? (b) What is a closed system?

Short Answer

Expert verified
(a) In thermodynamics, a system refers to a specific region of space chosen for study, defined by a boundary. The behavior of matter and energy inside this boundary are analyzed to understand various thermodynamic processes. (b) A closed system is a type of system where the mass within the system remains constant, meaning no mass enters or exits the defined boundary. However, energy, such as heat and work, can still be exchanged between the system and its surroundings.

Step by step solution

01

(Define System in Thermodynamics)

In thermodynamics, a system refers to a specific region of space that is chosen for study, usually defined by a boundary. The behavior of matter and energy inside this boundary are analyzed to understand various thermodynamic processes, such as heat transfer, energy conversion, and phase changes.
02

(Define Closed System)

A closed system is a type of system in thermodynamics where the mass within the system remains constant, meaning no mass enters or exits the defined boundary. However, energy, such as heat and work, can still be exchanged between the system and its surroundings. Closed systems are commonly used to study processes where energy transfer and transformation occur without the addition or loss of any substances.

A watt is a measure of power (the rate of energy change) equal to \(1 \mathrm{~J} / \mathrm{s}\). (a) Calculate the number of joules in a kilowatt-hour. (b) An adult person radiates heat to the surroundings at about the same rate as a 100 -watt electric incandescent lightbulb. What is the total amount of energy in kcal radiated to the surroundings by an adult in 24 hours?

From the enthalpies of reaction \(\begin{aligned} 2 \mathrm{H}_{2}(g)+\mathrm{O}_{2}(g) & \longrightarrow 2 \mathrm{H}_{2} \mathrm{O}(g) & \Delta H &=-483.6 \mathrm{~kJ} \\ 3 \mathrm{O}_{2}(g) & \cdots &-\cdots & 2 \mathrm{O}_{3}(g) & \Delta H &=+284.6 \mathrm{~kJ} \end{aligned}\) calculate the heat of the reaction $$ 3 \mathrm{H}_{2}(\mathrm{~g})+\mathrm{O}_{3}(\mathrm{~g}) \longrightarrow 3 \mathrm{H}_{2} \mathrm{O}(\mathrm{g}) $$

Two solid objects, \(\mathrm{A}\) and \(\mathrm{B}\), are placed in boiling water and allowed to come to temperature there. Each is then lifted out and placed in separate beakers containing \(1000 \mathrm{~g}\) water at \(10.0{ }^{\circ} \mathrm{C}\). Object \(\mathrm{A}\) increases the water temperature by \(3.50^{\circ} \mathrm{C} ; \mathrm{B}\) increases the water temperature by \(2.60^{\circ} \mathrm{C}\). (a) Which object has the larger heat capacity? (b) What can you say about the specific heats of A and B?

The standard enthalpies of formation of gaseous propyne \(\left(\mathrm{C}_{3} \mathrm{H}_{4}\right)\), propylene \(\left(\mathrm{C}_{3} \mathrm{H}_{6}\right)\), and propane \(\left(\mathrm{C}_{3} \mathrm{H}_{8}\right)\) are \(+185.4,+20.4\), and \(-103.8 \mathrm{~kJ} / \mathrm{mol}\), respectively. (a) Calculate the heat evolved per mole on combustion of each substance to yield \(\mathrm{CO}_{2}(g)\) and \(\mathrm{H}_{2} \mathrm{O}(g) .\) (b) Calculate the heat evolved on combustion of \(1 \mathrm{~kg}\) of each substance.

The heat of combustion of ethanol, \(\mathrm{C}_{2} \mathrm{H}_{5} \mathrm{OH}(l)\), is \(-1367 \mathrm{~kJ} / \mathrm{mol}\). A batch of Sauvignon Blanc wine contains \(10.6 \%\) ethanol by mass. Assuming the density of the wine to be \(1.0 \mathrm{~g} / \mathrm{mL}\), what caloric content does the alcohol (ethanol) in a 6-oz glass of wine (177 mL) have?
