Question

name:
fill in the blank: fill in the blank with the correct words.

1. is anything that has mass and takes up space.
2. the amount of matter in an object, which does not change based on location, is called its
3. the force that gravity exerts on an objects mass is known as its , and it can change depending on where you are.
4. a is the force that holds two or more atoms together in a molecule or compound.
5. a contains two or more substances that are physically combined but not chemically bonded, and its parts can be separated by physical means.
6. a is formed when two atoms of the same element are chemically bonded together.
7. a is formed when two or more atoms of different elements are chemically bonded together.
8. the attractive force between molecules is called
9. the energy that an object has due to its motion or simply energy in motion is called
10. an process is characterized by the absorption of energy.

write on the blank the state of matter described by each statement.

1. particles have the least amount of kinetic energy.
2. particles primarily vibrate in fixed positions.
3. the state that has the strongest intermolecular force
4. particles can move past one another but are still relatively close.
5. particles have the most kinetic energy.
6. particles move rapidly and freely, with high speeds and greater independence.
7. it is the state that has the weakest intermolecular force.
8. it follows the shape of the container but does not fill it up
9. it has a definite shape and volume.
10. it fills up the entire space of its container.

Explanation:

1. Matter is defined as anything that has mass and occupies space.
2. Mass is the measure of the amount of matter in an object, which is invariant to location.
3. Weight is the force exerted on an object's mass by gravity and can vary depending on location.
4. A chemical bond holds atoms together in a molecule or compound.
5. A mixture consists of two or more substances physically combined, separable by physical means.
6. A di - atomic molecule is formed when two atoms of the same element bond chemically.
7. A compound is formed by the chemical bonding of atoms of different elements.
8. Intermolecular force is the attractive force between molecules.
9. Kinetic energy is the energy of motion.
10. An endothermic process absorbs energy.

11 - 20: Solids have the least kinetic energy, particles vibrate in fixed positions, and have the strongest intermolecular force and a definite shape and volume. Liquids have particles that can move past one another and follow the shape of the container but don't fill it up. Gases have the most kinetic energy, particles move rapidly and freely, have the weakest intermolecular force, and fill up the entire space of the container.
