Questions

Fill the blanks with the right answers

$1-$ Heat is the Energy that flows as a result of between a and its surroundings.

$2-$ Work is defined a: when it is done by the system on the surroundings.

$3-$ The internal energy of a system depends on $$d

$4-$ Sublimation is Passing from the directly into the

$5-$ Superheated vapor: A vapor that is not about to

Choose the right answer

In Mass is transferred across the system boundaries while the process is taking place.

Sublimation

Open system

Closed system

is the rate of work done by the fluid at the system outlet minus rate of work done by the fluid at the system inlet

Flow work

Shaft work

The First Law of Thermodynamics is as following : Inlet Energy $+$ Heat $-$ Outlet Energy $-$ Work $=$

Sublimation

Potential energy

Accumulation

True or False :

$1-$ All energy possessed by a system, other than kinetic and potential energy $($

$2--$ The direction of flow is always from a lower temperature to a high one

$3-$ force, torque and a voltage are examples of work

$4-$ No mass is transferred across the system boundaries while the process is taking place, this process considered as Closed system

$5-$ If a system and its surroundings are at the same temperature or the system is perfectly insulated, then $Q=0,01$

$6-$ If there are no moving parts or electrical current at the system boundry then $W=0$

$7-$ Kinetic energy is the Energy due to the translational motion of the system $$
