Which of the following is an example of an isolated system?
Which of the following is an extensive property?
Sample Questions
Which of the following are state functions?
Show answer
Internal energy, Enthalpy
State functions depend only on the initial and final states of the system, not on the path taken. Internal energy (U) and enthalpy (H) are state functions, while heat (q) and work (w) are path-dependent.
Temperature is an intensive property because it does not depend on the amount of substance.
Show answer
True
Intensive properties like temperature, pressure, and density do not depend on the quantity of matter present in the system.
In an exothermic reaction, heat is absorbed from the surroundings.
Show answer
False
Exothermic reactions release heat to the surroundings, causing a temperature rise. Endothermic reactions absorb heat.
Which of the following processes occurs at constant temperature?
Show answer
Isothermal process
An isothermal process occurs at constant temperature, typically maintained by heat exchange with a reservoir.
