Answer:

Molecules in the hot water bottle are moving faster than the molecules of the skin.

Explanation:

When an object is heated, the molecules of that object move much faster than the room temperature object or a cold object. When the molecules move faster, the friction causes heat.

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.

The _______ gives the smallest whole number ratio of moles of each element in a compound. therefore, multiple compounds may have
nasty-shy [4]

The <u>Empirical formula</u> gives the smallest whole number ratio of moles of each element in a compound. therefore, multiple compounds may have it in common.

<h3>What is Empirical formula?</h3>

The most straightforward whole number ratio of atoms in a compound is its empirical formula. The empirical formula for sulfur monoxide, or SO, and disulfur dioxide, or S2O2, are both straightforward illustrations of this idea.

<h3>What is multiple compounds?</h3>

According to the law of multiple proportions, if two elements combine to form more than one compound, the ratio of the second element's mass to the fixed mass of the first element will always be a ratio of tiny whole numbers.

<h3>What is empirical formula used for?</h3>

Typically, the empirical formula is used to simply display the components of a molecule. When one needs to quickly identify the elements they are working with, this is helpful. When you want to know how many atoms of each element are present in the molecule, the molecular formula is most helpful.
