Question 1

Specific Volume equation

Answer 1

Specific Volume = Volume/Mass

Question 2

Density equation

Answer 2

Density = Mass/Volume and Density = 1/Specific Volume

Question 3

Specific Weight equation

Answer 3

Specific Weight = Gravity/Specific Volume

Question 4

What is Entropy (S)?

Answer 4

The measure of disorder.

Question 5

What is Enthalpy (H)?

Answer 5

It is the total measure of heat in a system.

Question 6

Internal energy….

Answer 6

only changes due to temperature change.

Question 7

Enthalpy equation

Answer 7

H = U+pv

Question 8

What is Specific heat capacity (Cp)?

Answer 8

The amount of energy it takes to raise 1 gram of matter 1 degrees celsius. Units = Joules/gram degree celsius.

Question 9

Heat Transfer Equation (Q)

Answer 9

Q = mass x Specific heat capacity x change in temp

Question 10

What is Work done to the system and work done by the system.

Answer 10

Work done to the system is when surroundings transfer energy to the system (negative). Work done by the system is when energy is transferred to the surroundings by the system (positive).
