1 / 15

Why is steam used in a steam engine?

Because of water's high heat of vaporization

Due to its ability to condense quickly

Due to its low heat of vaporization

Because of water's high freezing point

2 / 15

The boiling point of water at sea level is:

212 °F

154 °F

180 °F

39.16 °F

3 / 15

What is the fundamental action of the plant?

Cooling down the core temperature

Moving water from one location to another

Generating steam from pure water

Controlling radiation levels in the environment

4 / 15

Which of the following statements is true about metals?

Metals do not have free-moving electrons

Metals are poor conductors because of their ionic bonds

Metals do not form a crystalline structure

Metals are usually the best conductors of thermal energy

5 / 15

In forced convection:

The fluid remains stationary, allowing heat transfer

Heat is transferred only through natural circulation

The fluid relies on buoyancy due to gravity

A pump, fan, or other means is used to propel the fluid

6 / 15

An open cooling water system is characterized by:

Being open to the atmosphere

Not needing any makeup

Having a surge tank

Being sealed off from the atmosphere

7 / 15

Natural convection relies on which driving force?

Buoyancy due to fluid density differences

Temperature change

Pressure

Pumping mechanism

8 / 15

The function of the individual systems that make up the plant is achieved by:

Avoiding the use of steam

Using basic components in different combinations

Only moving water

Creating new components

9 / 15

A heat exchanger is a component that:

Cools down substances to the same temperature

Only transfers heat to a hotter substance

Stops the flow of heat altogether

Transfers heat between two substances at different temperatures

10 / 15

Steam, in its purest form, is:

A liquid

A solid

A white mist seen above boiling water

A completely invisible gas

11 / 15

Which property describes water's ability to stick to itself?

Adhesion

Solvent capability

Cohesion

Conductivity

12 / 15

Most of the heat exchangers in the plant are:

Counter flow

Crossflow

Parallel flow

Turbulent flow

13 / 15

In most heat exchangers, the higher pressure fluid is:

Equally distributed

On the shell side

Inside the tubes

Outside the tubes

14 / 15

What is the chemical formula for water?

CO2

H2O

15 / 15

Convection heat transfer in the plant heat exchangers is a combination of:

Natural circulation and forceful circulation

Transfer of heat in a solid and in a vacuum

Conduction heat transfer and transfer of heat with a fluid in motion

Ionic and covalent bonding
