, CYU - Check Your Understanding




CYU 1-1 ■ Check Your Understanding

CYU 1-1.1 Choose the wrong statement about the first law of thermodynamics.
During an interaction, energy can change from one form to another.
During an interaction, the total amount of energy remains constant.
Energy can be destroyed but it cannot be created.
Energy is a thermodynamic property.
A system with more energy input than output will gain energy.

Answer: (c) Energy can be destroyed but it cannot be created.

CYU 1-1.2 Which statement best expresses the second law of thermodynamics?
The temperature of a well-sealed room increases when a fan in the room is turned on.
A cup of cool coffee in a warm room never gets hot by itself.
Heat is generated when there is friction between two surfaces.
A household refrigerator supplies heat to the kitchen when operating.
A person who has a smaller energy input than output will lose weight.

Answer: (b) A cup of cool coffee in a warm room never gets hot by itself.

, CYU 1-2.3 What is the weight of 10 kg?

10 N
10 lbf
9.8 N
98 N
322 lbf

Answer: (d) 98 N



𝑊 = mg = (10 kg)(9.8 𝑚/𝑠2) = 98 kg ·
𝑚/𝑠2 = 98 𝑁
CYU 1-3 ■ Check Your Understanding
CYU 1-3.1 Choose the wrong statement regarding systems and control volumes.
(a) The mass or region outside the system is called the surroundings.
(b) The real or imaginary surface that separates the system from its surroundings is called the boundary.
(c) The boundary has zero thickness.
(d) The boundary can neither contain any mass nor occupy any volume in space.
(e) The boundary of a system is fixed; it cannot move.

Answer: (e) The boundary of a system is fixed; it cannot move.


CYU 1-3.2 Choose the wrong statement regarding systems and control volumes.
(a) Both mass and energy can cross the boundary of a control volume.
(b) Mass cannot enter or leave a closed system but energy can.
(c) Mass can enter or leave an isolated system but energy cannot.
(d) The boundaries of a control volume can be real or imaginary.
(e) The volume of a closed system does not have to be fixed.

Answer: (c) Mass can enter or leave an isolated system but energy cannot.
