Q

Gas molecules are small compared to the distances between them and that they are in constant random motion.
Their kinetic energy does not change with time as long as the temperature remains the same.
Higher the temperature, the greater the motion.

Q

17
Q

Two main characteristics are that they include carbon and are formed by covalent bonds.
Melt at temperatures below 300

A

Organic Compounds

18
Q

Generalized principles dealing with energy and heat

A

Laws of thermodynamics

19
Q

Two objects in thermodynamic equilibrium with the third object are also in equilibrium with each other. Being in thermodynamic equilibrium basically means that different objects are at the same temperature.

A

Zeroth law

20
Q

Deals with conservation of energy. It states that neither mass nor energy can be destroyed; only converted from one form to another.

A

First law

21
Q

States that the entropy (the amount of energy in a system that is no longer available for work or the amount of disorder in a system) of an isolated system can only increase. It also states that heat is not transferred from a lower-temperature system to a higher-temperature one unless additional work is done.

A

Second law

22
Q

State that as temperature approaches absolute zero, entrophy approached a constate minimum. It also states that a system cannot be cooled to absolute zero.

A

Third law

23
Q

Energy transfer from one body or system to another due to thermal contact

A

Heat

24
Q

Measurement of an object’s stored heat energy and is the average kinetic energy of an object’s particles. When the temperature of an object increases and its atoms move faster, kinetic energy also increases.

A

Temperature

25
Q

Measure of the amount of substance in an object

A

Mass

26
Q

Measure of the gravitational pull of Earth on an object

A

Weight

27
Q

Measure of the amount of space occupied.

A

Volume

28
Q

Measure of the amount of mass per unit volume.

D=m/V

A

Density

29
Q

Measure of the ratio of a substance’s density compared to the density of water

A

Specific Gravity

30
Q

Energy transferred to a body by a means other than work.

A

Thermal contact
