Interpretation: Whether the combustion of gasoline in a car engine is an exothermic or endothermic process should be determined.
Concept Introduction: Endothermic and exothermic processes are defined on the basis of energy involved. The addition of energy is endothermic whereas loss of energy is exothermic.

Answer to Problem 60A
The combustion of gasoline in a car engine is an exothermic process.
Explanation of Solution
The combustion of gasoline in a car engine releases energy which is helpful in running the car engine. Since, the energy is released during the combustion of gasoline in a car engine from system to the surroundings so, it is an exothermic process.
Interpretation: Whether the condensing of water in a cold pipe is an exothermic or endothermic process should be determined.
Concept Introduction: Endothermic and exothermic processes are defined on the basis of energy involved. The addition of energy is endothermic whereas loss of energy is exothermic.

Answer to Problem 60A
The condensing of water in a cold pipe is an exothermic process.
Explanation of Solution
The condensing of water in a cold pipe releases energy that is in condensation process, the water changes its phase from vapor to liquid by releasing energy. Since, the energy is released during condensing of water in a cold pipe from system to the surroundings so, it is an exothermic process.
Interpretation: Whether
Concept Introduction: Endothermic and exothermic processes are defined on the basis of energy involved. The addition of energy is endothermic whereas loss of energy is exothermic.
