What information can be found in the steam tables?

• The velocity of steam at different pressures

• The volume of the water at different temperatures

• The temperature of the steam at different pressures

• The sensible heat added to the steam at different pressures

What is the correct definition of saturated steam?

• Steam at the same temperature as the water from which it was produced

• Steam with all water droplets removed

• Steam to which sensible heat has been added

• Steam that has been completely heated and no additional heat can be added

What effect does lowering the pressure have on the boiling temperature of water?

• Boiling temperature remains constant

• Boiling temperature increases

• Boiling temperature decreases

What does the temperature column indicates in a typical steam table?

• The temperature of the steam only

• The boiling temperature only

• The temperature of the condensate only

• The boiling temperature and the temperature of the steam

What does the sensible heat column indicate on a typical steam table?

• The amount of heat energy required to raise the temperature of a mass of water to the boiling temperature

• The amount of heat energy required to raise the temperature of 1 lb of water from 32°F to 212°F

• The amount of heat energy required to change the state of 1 lb of water to 1lb of steam

• The amount of heat energy required to raise the temperature of 1 lb of water from 32°F to the boiling temperature of the water

What is the relationship between pressure and the volume of steam?

• pressure increases, volume increases

• pressure increases, volume remains constant

• pressure decreases, volume increases

• pressure decreases, volume remains constant

What is the relationship between temperature and pressure?

• pressure increases, temperature increases

• pressure increases, temperature remains constant

• pressure decreases, temperature increases

• pressure decreases, temperature remains constant
