What is the chemical formula for water?

CO2

H2O

2 / 15

Steam, in its purest form, is:

A white mist seen above boiling water

A solid

A liquid

A completely invisible gas

3 / 15

An open cooling water system is characterized by:

Being open to the atmosphere

Having a surge tank

Being sealed off from the atmosphere

Not needing any makeup

4 / 15

Natural convection relies on which driving force?

Pressure

Buoyancy due to fluid density differences

Temperature change

Pumping mechanism

5 / 15

Which of the following statements is true about metals?

Metals do not form a crystalline structure

Metals are poor conductors because of their ionic bonds

Metals are usually the best conductors of thermal energy

Metals do not have free-moving electrons

6 / 15

What is the fundamental action of the plant?

Generating steam from pure water

Cooling down the core temperature

Controlling radiation levels in the environment

Moving water from one location to another

7 / 15

A heat exchanger is a component that:

Only transfers heat to a hotter substance

Stops the flow of heat altogether

Cools down substances to the same temperature

Transfers heat between two substances at different temperatures

8 / 15

Most of the heat exchangers in the plant are:

Crossflow

Counter flow

Turbulent flow

Parallel flow

9 / 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

Creating new components

Only moving water

10 / 15

The boiling point of water at sea level is:

39.16 °F

180 °F

154 °F

212 °F

11 / 15

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

Solvent capability

Cohesion

Adhesion

Conductivity

12 / 15

In forced convection:

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

Heat is transferred only through natural circulation

The fluid remains stationary, allowing heat transfer

The fluid relies on buoyancy due to gravity

13 / 15

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

Ionic and covalent bonding

Transfer of heat in a solid and in a vacuum

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

Natural circulation and forceful circulation

14 / 15

In most heat exchangers, the higher pressure fluid is:

On the shell side

Outside the tubes

Inside the tubes

Equally distributed

15 / 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
