Energy and Steam Fundamentals

Question 1

Is temperature a measure of heat?

Answer 1

no

Question 2

What happens to all the heat during the evaporation process with the temperature remaining constant?

Answer 2

the latent heat is absorbed in providing the energy to bring about the transformation from water to steam

Question 3

Adding additional heat to saturated steam causes the steam temperature to?

Answer 3

Rise

Question 4

What happens if only 90% of latent heat is provided?

Answer 4

Only 90% of the water will be converted into steam, resulting in wet steam with a wetness factor of 10%

Question 5

Given that steam has a specific heat of 0.5 it requires _____ as much heat input as water to cause a given temperature rise

Answer 5

half

Question 6

Adding additional heat to saturate steam is known as?

Answer 6

Superheated steam

Question 7

What is the temperature of saturated steam at atmospheric pressure?

Answer 7

100DegC

Question 8

What is heat?

Answer 8

heat is the quantity that represents energy, the ability to perform work

Question 9

What is the heat energy required to heat water to steam at 1atm?

Answer 9

2257kJ/kg

Question 10

As the pressure increases what does the boiling point, latent heat and specific volume do?

Answer 10

Increases. Latent heat decreases. specific volume does not change
