HACTEHA [7]

I can deduce here that the best that describes my choice is: It’s my best explanation for now, but I really would have to test my idea to be sure.

<h3>What is choice?</h3>

Choice actually refers to the act of choosing between two or more things. It has to do with going with the option, idea, decision, product or something that one prefers.

When we make choices, it depicts what we actually want. Some people still make wrong choices. The choices people make can either make or mar them in the present or future.

Graph of the relationship between mass and thermal energy
elixir [45]

<em>Thermal energy</em> is the sum of the kinetic and potential energies of all the particles in an object.

Assume that you have 250 gL of water and 1 kg of water at the same temperature.

Then, each water molecule has the same kinetic energy.

The larger sample contains four times as many molecules, so it contains four times as much thermal energy.

Thus, thermal energy is directly proportional to mass.

In symbols, <em>KE </em>∝ <em>m</em> or <em>KE = km</em>.

The graph of a direct proportion is a <em>straight line passing trough the origin</em>.

It should look something like the graph below.

Arrange the following elements in order of increasing (from smallest to largest) atomic size: H, Br, Cl, O. Explain the reasonin
juin [17]

Explanation:

Atomic size is defined as the distance between the nucleus and valence shell of an atom. Valence shell is the outermost shell of an atom.

When we move across a period in a periodic table then there will occur a decrease in atomic size of the atoms. But when we move across a group in a periodic table then there will occur an increase in atomic size of the atom.

Hydrogen is a period 1 element, oxygen is a period 2 element, chlorine is a period 3 element and bromine is a period 4 element.

Therefore, given elements are arranged in order of increasing atomic size as follows.

                             H < O < Cl < Br
