Worked practice questions

In an isothermal process the quantity held fixed is the:

  1. Entropy one
  2. Temperature
  3. Pressure one
  4. Volume one
Show answer and solution

Correct answer: B. Temperature

1. The name of the process says what stays the same. 2. Iso means equal and thermal refers to heat. 3. The temperature is held fixed. _Source: syllabus Physics Part II, Chapter 12, Thermodynamics._

For an ideal gas in an isothermal process, PV stays:

  1. Falling
  2. At zero
  3. Constant
  4. Rising up
Show answer and solution

Correct answer: C. Constant

1. The ideal gas equation ties P, V and T together. 2. With T fixed, the product of P and V cannot change. 3. So PV stays constant. _Source: syllabus Physics Part II, Chapter 12, Thermodynamics._

Gas expanding in a cylinder inside a large fixed temperature reservoir is:

  1. Adiabatic
  2. Isochoric
  3. Isobaric
  4. Isothermal
Show answer and solution

Correct answer: D. Isothermal

1. The reservoir holds the temperature steady throughout. 2. Heat flows in without changing that temperature. 3. So the expansion is an isothermal process. _Source: syllabus Physics Part II, Chapter 12, Thermodynamics._
