FUN 2 EO: 1.4-f

1 / 15

Steam, in its purest form, is:

A white mist seen above boiling water

A solid

A completely invisible gas

A liquid

2 / 15

What is the chemical formula for water?

H2O

CO2

3 / 15

Which of the following statements is true about metals?

Metals are usually the best conductors of thermal energy

Metals do not form a crystalline structure

Metals do not have free-moving electrons

Metals are poor conductors because of their ionic bonds

4 / 15

A heat exchanger is a component that:

Stops the flow of heat altogether

Only transfers heat to a hotter substance

Cools down substances to the same temperature

Transfers heat between two substances at different temperatures

5 / 15

Why is steam used in a steam engine?

Due to its low heat of vaporization

Because of water's high freezing point

Because of water's high heat of vaporization

Due to its ability to condense quickly

6 / 15

Most of the heat exchangers in the plant are:

Parallel flow

Crossflow

Counter flow

Turbulent flow

7 / 15

In most heat exchangers, the higher pressure fluid is:

Inside the tubes

On the shell side

Outside the tubes

Equally distributed

8 / 15

An open cooling water system is characterized by:

Being sealed off from the atmosphere

Not needing any makeup

Being open to the atmosphere

Having a surge tank

9 / 15

In forced convection:

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

The fluid relies on buoyancy due to gravity

Heat is transferred only through natural circulation

The fluid remains stationary, allowing heat transfer

10 / 15

The boiling point of water at sea level is:

39.16 °F

154 °F

212 °F

180 °F

11 / 15

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

Natural circulation and forceful circulation

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

Ionic and covalent bonding

Transfer of heat in a solid and in a vacuum

12 / 15

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

Avoiding the use of steam

Creating new components

Only moving water

Using basic components in different combinations

13 / 15

Natural convection relies on which driving force?

Temperature change

Pressure

Buoyancy due to fluid density differences

Pumping mechanism

14 / 15

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

Solvent capability

Cohesion

Conductivity

Adhesion

15 / 15

What is the fundamental action of the plant?

Cooling down the core temperature

Generating steam from pure water

Controlling radiation levels in the environment

Moving water from one location to another
