(a)
Interpretation:
The three ways by which internal energy can be increased of an open system has to be explained.
Concept Introduction:
The regions of interest in which the reaction are taking place are considered as the system whereas everything else is said to be surrounding. The system is said to be open system which can exchange both matter and the energy with the surroundings. The system is said to be closed system when it can exchange the energy with the surroundings but cannot exchange the matter.
(b)
Interpretation:
The method which is used to increase the internal energy of a closed system has to be explained.
Concept Introduction:
Same as part (a).
(c)
Interpretation:
The method which is used to increase the internal energy of an isolated system has to be explained.
Concept Introduction:
Same as part (a).

Chemical Principles: The Quest for Insight
- Under what circumstances is the heat of a process equal to the enthalpy change for the process?arrow_forwardWhat are the two ways that a final chemical state of a system can be more probable than its initial state?arrow_forwardWould the amount of heat absorbed by the dissolution in Example 5.6 appear greater, lesser, or remain the same if the heat capacity of the calorimeter were taken into account? Explain your answer.arrow_forward
- Nitrogen gas (2.75 L) is confined in a cylinder under constant atmospheric pressure (1.01 105 pascals). The volume of gas decreases to 2.10 L when 485 J of energy is transferred as heat to the surroundings. What is the change in internal energy of the gas?arrow_forwardWhen one mol of KOH is neutralized by sulfuric acid, q=56 kJ. (This is called the heat of neutralization.) At 23.7C, 25.0 mL of 0.475 M H2SO4 is neutralized by 0.613 M KOH in a coffee-cup calorimeter. Assume that the specific heat of all solutions is 4.18J/gC, that the density of all solutions is 1.00 g/mL, and that volumes are additive. (a) How many mL of KOH is required to neutralize H2SO4? (b) What is the final temperature of the solution?arrow_forwardYou did an experiment in which you found that 59.8 J was required to raise the temperature of 25.0 g of ethylene glycol (a compound used as antifreeze in automobile engines) by 1.00 K. Calculate the specific heat capacity of ethylene glycol from these data.arrow_forward
