The periodic table is called "periodic" because the chemical properties of elements repeat each period.

Answer:

false

Explanation:

It is called the periodic table because of the way the elements are arranged. You'll notice they're in rows and columns. The horizontal rows (which go from left to right) are called 'periods' and the vertical columns (going from up to down) are called 'groups'.

Different amounts of ice was added to several samples of water. The results are shown in the table. Which conclusion can be draw
Yakvenalex [24]

The conclusion which can be drawn from the results that more ice added caused a greater change in temperature.

<h3>Why temperature of substance changes?</h3>

Temperature of any substance will change if some amount of energy is absorbed or released by that substance in the form of heat.

If in simple water, we add some amount of ice then energy or heat from the whole mixture will released as a result of which temperature of the water decreases. And decrease in temperature will depend on the amount of added ice.

Hence, more ice added caused a greater change in temperature.

What is the relationship between the motion of the water molecules and the heat added to or removed from the system in the simul
Sergio [31]

Answer:

The motion of the water molecules increase as heat is added.

Explanation:

Hello!

In this case, in general terms, one can know that molecules and heat have a relationship by which one affects the other, more specifically, the heat affects how the molecules behave. In such a way, as the heat added to a system increases its internal energy, one can notice that energy speeds up the molecules because they acquire such energy and the motion starts being increased, it means, the molecules start moving or vibrating faster than before of that heat addition. This is due to the increase of the internal energy, which based on the first law of thermodynamics is related with the velocity of the molecules.

Best regards!
