The average kinetic energy of 1 mole of a gas at -32 degrees Celsius is:
 
3.80 x 103 J

The relationship between volume and temperature of a gas, when pressure and moles of a gas are held constant, is: V*T = k.

FALSE

The relationship between moles and volume, when pressure and temperature of a gas are held constant, is: V/n = k. We could say then, that:
If the moles of gas are tripled, the volume must also triple.


 If the temperature and volume of a gas are held constant, an increase in pressure would most likely be caused by an increase in the number of moles of gas.

TRUE

If the vapor pressure of a liquid is less than the atmospheric pressure, the liquid will not boil.

TRUE


35 - AB

36 -  BD

33 - true

34 - False

20 - 6

21 - orthohombic

The water makes your individual hairs stick close together. ... When more light is absorbed by your wet hair, less light gets reflected back to your eyes. The result is that your hair appears darker than when it's dry.

Thermal energy added to a substance that is not changing state causes the substance’s temperature to
tatyana61 [14]

Answer:

increase

Explanation:

Conduction involves the transfer of electric charge or thermal energy due to the movement of particles. When the conduction relates to electric charge, it is known as electrical conduction while when it relates to thermal energy, it is known as heat conduction. Conductors include metal, steel, aluminum, copper, frying pan, pot, spoon etc.

In the process of heat conduction, thermal energy is usually transferred from fast moving particles to slow moving particles during the collision of these particles. Also, thermal energy is typically transferred between objects that has different degrees of temperature and materials (particles) that are directly in contact with each other but differ in their ability to accept or give up electrons.

Hence, thermal energy added to a substance that is not changing state causes the substance’s temperature to increase because it would absorb energy in the form of heat.

A scientist is working in a lab and accidentally combines two liquids that quickly form a solution. Which process could be used
PIT_PIT [208]

Answer:

Distillation

Explanation:

The method of distillation can be used to separate the two liquids, if their boiling point is known. The liquid with lower boiling point will be evaporated and its vapours will be captured, while the liquid with higher boiling point will remail in the container in the liquid state.
