Chapter 6: Problem 29

What is the difference between specific heat and heat capacity? What are the units for these two quantities? Which is the intensive property and which is the extensive property?

Short Answer

Expert verified
Specific Heat is the heat capacity per unit mass and it's an intensive property measured in Joule per kilogram per Kelvin (J/kg.K). Heat Capacity is the heat to be supplied to induce a unit temperature change and it is an extensive property measured in Joule per Kelvin (J/K).

Step by step solution

01

Comparison

Specific Heat is the amount of heat per unit mass required to raise the temperature by one degree Celsius. On the other hand, Heat Capacity is the measure of the amount of heat to be supplied to a given substance to produce a unit change in its temperature. In other words, Specific Heat is the heat capacity per unit mass.
02

Measurement Units

The standard unit of Specific Heat in the International System of Units (SI) is Joule per kilogram per Kelvin (J/kg.K). Heat Capacity, on the other hand, is measured in Joule per Kelvin (J/K).
03

Classification into Intensive and Extensive Properties

An intensive property does not depend on the amount of substance, while an extensive property does. Therefore, Specific Heat is an Intensive property as it does not depend on the mass of the substance. In contrast, Heat Capacity is an Extensive property since it depends on the amount of substance.

Producer gas (carbon monoxide) is prepared by passing air over red-hot coke: $$ \mathrm{C}(s)+\frac{1}{2} \mathrm{O}_{2}(g) \longrightarrow \mathrm{CO}(g) $$ Water gas (mixture of carbon monoxide and hydrogen) is prepared by passing steam over red-hot coke: $$ \mathrm{C}(s)+\mathrm{H}_{2} \mathrm{O}(g) \longrightarrow \mathrm{CO}(g)+\mathrm{H}_{2}(g) $$ For many years, both producer gas and water gas were used as fuels in industry and for domestic cooking. The large-scale preparation of these gases was carried out alternately, that is, first producer gas, then water gas, and so on. Using thermochemical reasoning, explain why this procedure was chosen.

A piece of silver of mass \(362 \mathrm{~g}\) has a heat capacity of \(85.7 \mathrm{~J} /{ }^{\circ} \mathrm{C}\). What is the specific heat of silver?

Explain the meaning of this thermochemical equation: $$ \begin{aligned} 4 \mathrm{NH}_{3}(g)+5 \mathrm{O}_{2}(g) \longrightarrow 4 \mathrm{NO}(g) &+6 \mathrm{H}_{2} \mathrm{O}(g) \\ \Delta H=&-904 \mathrm{~kJ} / \mathrm{mol} \end{aligned} $$

A truck initially traveling at \(60 \mathrm{~km}\) per hour is brought to a complete stop at a traffic light. Does this change violate the law of conservation of energy? Explain.

The internal energy of an ideal gas depends only on its temperature. Do a first-law analysis of this process. A sample of an ideal gas is allowed to expand at constant temperature against atmospheric pressure. (a) Does the gas do work on its surroundings? (b) Is there heat exchange between the system and the surroundings? If so, in which direction? (c) What is \(\Delta E\) for the gas for this process?
