bearhunter [10]

Answer:

B) As you move across the row, the number of electrons increases and reactivity also increases.

Explanation:

The periodic table is arranged in a way that if you go across a period, the number of protons, neutrons, and electrons in an element increases. In terms of reactivity, the most reactive elements are the ones which have a high electronegativity. The electronegativity of the elements increases as you travel to the right and upwards on the periodic table.

A student observes that water in a pot on a burner becomes hotter explain how energy is conserved in the situation
Daniel [21]

  • The water in the pot becomes hotter as a result of heat transfer.

  • <em>Energy can be transferred from a region to another , but there will still the same overall amount of energy</em> ( energy conservation)

  • When a pot containing water  is  placed on the stove and  heat is applied with the burner, there is a flow of heat from the burner to the water.

  • Heat will be transferred from the burner to the pot, then there will be transferred of heat from the pot to the water, the molecules there in the water  will be energized as a result of the heat transfer until the boiling point  is  reached.

  • Energy transfer can take place in three form, this could be conduction, radiation or convention.

  • Convention which is a cyclical process is the one that occurs in fluids only so as a result of convection , the water at the bottom will be heated and the molecules start moving and it will rise till it get to the water at the top of the pot.

<em>Therefore, the water is heated as a result of heat transfer.</em>
