Q11. A thermodynamic system that cannot exchange either mass or energy with its surroundings is called a/an:
Correct Answer: C. An isolated system is completely cut off from surroundings, preventing both mass and energy exchange.
Q12. According to the First Law of Thermodynamics, which mathematical formula represents the conservation of system internal energy?

Correct Answer: C. Law #3 on page 8 confirms that cooling a perfect crystalline setup down to absolute zero minimizes structural disorder near zero.
Q17. If you squeeze a gas balloon and reduce its volume ($\Delta V$ is negative), what are the resulting signs for work (w) based on $w = -P\Delta V$?
Correct Answer: B. Squeezing cuts down volume (negative $\Delta V$). Multiplying a negative change by $-P$ yields a positive work value, showing work is added to the system.
Q18. If an expanding gas system pushes against surroundings to increase its volume ($\Delta V$ is positive), the value of work (w) is:
Correct Answer: B. A positive expansion change combined with the negative coefficient in $w = -P\Delta V$ creates a negative work value, meaning the system works on its surroundings.
Q19. Thermodynamics can determine if a specific process will take place naturally, but it CANNOT determine:
Correct Answer: C. Page 2 explicitly states that thermodynamics evaluates whether a reaction will happen, but measuring the actual speed requires checking kinetics instead.
Q20. Together, the target reactive chemical system and its surrounding environmental container are defined as the:
Correct Answer: C. Page 6 establishes that the system plus its surroundings combined are called the universe.

Q22. An endothermic process is one that consumes heat from its surroundings, meaning its $\Delta H$ or q value is:
Correct Answer: B. Page 13 states that endothermic processes draw in heat and always have a positive enthalpy change value ($\Delta H > 0$).
Q23. Based on the standard states discussed in the text, what is the value of the enthalpy of formation for $H_2$ gas at 298 K and 1 atm?
Correct Answer: C. Page 25 confirms that the enthalpy of formation ($\Delta H^\circ_f$) for any element in its standard state, such as $H_2$ gas, is exactly 0 kJ/mol.
Q24. In contrast to standard gas conditions, the textbook notes that the enthalpy of formation for liquid or solid hydrogen is:
Correct Answer: B. Page 25 notes that since gas is the only true standard state for hydrogen at 298 K, solid or liquid forms of hydrogen do not have an enthalpy of formation equal to zero.
Q25. Which of the following carbon allotropes serves as the standard baseline form with an enthalpy of formation value equal to 0 kJ/mol?
Correct Answer: B. The table on page 25 explicitly highlights that carbon in its graphite form is the reference standard state with a formation energy of zero.
Q26. An enthalpy of formation tracks the change in enthalpy ($\Delta H$) when creating how many moles of a single target substance from its raw parent elements?
Correct Answer: A. Page 25 notes that an enthalpy of formation tracks the exact energy change during the production of one mole of a compound.
Q27. The calorie (cal) is defined as the exact amount of heat energy required to raise the temperature of 1.0 gram of liquid water by:

Q29. Consider the phase changes. Which of the following processes requires a net consumption of heat (endothermic, $+\Delta H$)?
Correct Answer: B. The phase change summary card on page 14 highlights melting (fusion) as a process that absorbs heat energy ($+\Delta H$).
Q30. Given the general equation $\Delta H_{rxn} = \Sigma nH_{products} – \Sigma nH_{reactants}$, if the total enthalpy of the products is lower than that of the reactants, the reaction will be:
Correct Answer: B. Subtracting a larger reactant value from a smaller product value results in a negative $\Delta H$, which signifies an exothermic reaction.
