Thermodynamics Quiz

Thermodynamics is a branch of science that deals with:

• Only heat transfer

• Only work done

• Heat, work, and energy transformations

• Chemical reactions only

Which of the following is NOT a direct application of engineering thermodynamics?

• Power plants

• Refrigeration systems

• Automobile engines

• Designing computer software

The primary purpose of a refrigerator, from a thermodynamic perspective, is to:

• Generate heat

• Convert heat into work

• Transfer heat from a cold space to a warmer one

• Create energy

In a thermal power plant, the main principle applied is the conversion of:

• Mechanical energy to electrical energy

• Heat energy to mechanical work (to produce electricity)

• Chemical energy to light energy

• Electrical energy to heat energy

Which of these everyday processes heavily relies on thermodynamic principles?

• Cooking food on a stove

• Typing on a keyboard

• Painting a wall

• Reading a book

A defined quantity of matter or a region in space chosen for study is called a:

• Surroundings

• Boundary

• System

• State

Everything external to the system that interacts with it is known as the:

• Boundary

• Control volume

• Surroundings

• Control mass

The real or imaginary surface that separates the system from its surroundings is called the:

• Interface

• Boundary

• Wall

• Envelope

The condition of a system at a particular instant, defined by its properties, is called its:

• Process

• Cycle

• Phase

• State

A series of processes that eventually returns the system to its initial state is called a:

• Process

• Path

• Cycle

• Equilibrium
