Heat, Work, and Internal Energy Thermodynamic Processes Odds and Ends Definitions Laws Of Thermodynamics

When work transfers energy to a substance, does internal energy increase or decrease?

Increase

The internal energy of a substance or combination of a substance has been treated as a single quality to which added or from which energy is taken away. What is this combination of substances called?

A system

The ________ is the surroundings with which the system interacts.

Environment

Energy Transferred as heat turns water into steam. Energy from the steam does ______ against the force exerted by air _______ the balloon.

Work, Outside

G: A= m 2 d= 0.050m P= 7.5 x 10 5 Pa= 7.5 x 10 5 N/m U: ΔV=? W=? ΔV= Ad W=PΔV

ΔV= W=

The Symbol for internal energy is _____.

U

A thermodynamic process that takes place at constant volume so that no work is done on by the system.

What is the isovolumetric process?

A thermodynamic process that takes place at constant temp. and in which the internal energy of a system remains unchanged.

What is the isothermal process?

A thermodynamic process during which work is done on or by the system but no energy is transferred to or from the system as heat.

What is the adiabatic process?

“Iso”, as in isovolmic, means_______.

Constant

mgh + work

What does W equal?

On the highest point of the roller coaster the _______ is the highest.

P.E.

Idea of ordered energy tending to disordered energy is embodied.

What is entropy?

Increase, Increase

Any chemical reaction that _______ the number of gas molecules also increases entropy.

Increases

Study of heat- it’s transformation

What is thermodynamics?

The limit of temperature.

What is absolute zero?

Law of energy conservation is applied to thermal system

What’s the first law of thermodynamics?

Process of compression or expansion of a gas so that no heat enters or leaves a system.

What is adiabatic?

Heat will never flow from a cold object to a hot object.

What is the 2 nd law of thermodynamics?

If work is put into a heat engine, the flow of energy may go from a ____ temperature to a -_____ temperature place, as in a refrigerator or conditioner.

Low, High

Ideal efficiency of a heat engine

What is Carnot efficiency?

Some amount of energy in a reaction is always ____ to _____.

Lost, Heat
