During cooling, the kinetic energy of the molecules falls. Why does this happen?
katrin [286]

<span>During cooling, the kinetic energy of the molecules falls, be</span>cause, when cooling a substace, the particles (molecules) slow down.


The kinetic energy is related to the speed, such that the lower speed the lower kinetic energy.


Particles can translate and vibrate, in the case of gases and liquids, and only vibrate (in the case of solids).


As a substance is cooled the particles get closer and the motion (translation and vibration), slows down. You can see by the equation of the kinetic energy (KE):


KE = [1/2]mass×(speed)² that as the speed is lower the KE will also be lower.


Additionally, when the cooling does not drive a change of phase (gas to liquid, liquid to solid, or solid to gas), it drives a decrease on temperature. In this case you should know that the temperature is a measure of the kinetic energy: the lower the temperature, the lower the kinetic energy.

What is the mass of 4,48 L of SO2 at STP?
Trava [24]

Answer:

2 moles

Explanation:

Hi there !!

Molar volume = 22.4 litres

No: of moles = Given volume / Molar volume

                    = 44.8 / 22.4 = 2 moles

1. Freon (CCl2F2) is commonly used in refrigerators and air conditioners as a coolant. How many grams of fluorine are there in t
Georgia [21]

Answer:

285g of fluorine

Explanation:

To solve this problem we need to find the mass of Freon in grams. Then, with its molar mass we can find moles of freon and, as 1 mole of Freon, CCl₂F₂, contains 2 moles of fluorine, we can find moles of fluorine and its mass:

<em>Mass Freon:</em>

<em>2.00lbs * (454g / 1lb) = </em>908g of Freon

<em>Moles freon -Molar mass: 120.91g/mol- and moles of fluorine:</em>

908g of Freon * (1mol / 120.91g) =

7.5 moles of freon * (2moles Fluorine / mole Freon): 15 moles of fluorine

<em>Mass fluorine -Atomic mass: 19g/mol-:</em>

15 moles F * (19g / mol) =

<h3>285g of fluorine</h3>
