Answer</h2>
The physical state of the elements depends upon the <u>attraction forces </u>and their <u>kinetic energy</u>.
<h2>
Explanation</h2>
The elements or substances are fixed with each other with the help of different chemical forces including ionic bonding, covalent bonding, H- bonding etc. The strength of these forces is also one of the factors that affect their physical natures. For example, covalent or ionic bonds are the strongest bonds than all other bonds and metals that contain these forces are mostly in solid form. The kinetic motion of electrons in the element also affects the physical state of the element and potential of bonding.
Answer:
The molecule of gases are separated at far distance from each other in space causing the objects to move freely resulting in the increase in kinetic energy of the molecules.
Explanation:
There are 3 states of matters namely; solid, liquid and gaseous state.
For gases, the molecules are held father apart as such they possesses weak intermolecular force due to the large distance between their molecules. Due to the free nature of this molecules, they are free to move about in space leading to the increase in their kinetic energy. This molecules also tends to collide with one another and the walls of their container causing an increase in their kinetic energy and causing them to move faster in space.
Answer:
D
Explanation:
LA FUERZA NETA ES LA FUERZA TOTAL DE EMPUJE MENOS EL PESO DEL
COHETE.
= 700000 N(sen 90° - 20°) - 560000 N = 97785 N
Nuclear forces means are the forces that act between two or more nucleons. They bind protons and neutrons into atomic nuclei. The nuclear force is about 10 millions times stronger than the chemical binding that holds atoms together in molecules.
An endothermic reaction is the one that use : Chemical energy
Chemical energy refer to the energy that is stored within the bound of the compound (endothermic reaction absorb heat to produce energy)
