Here is the correct matching of each definition with its corresponding vocabulary term from the topic Chemistry: Behavior of Gases:
---
1. Process by which particles of matter fill in a space because of random motion
✔ Diffusion
> *Explanation:* Diffusion is the net movement of particles from an area of higher concentration to an area of lower concentration due to their random thermal motion. This is how gases spread out to fill their container.
---
2. A flowing, compressible substance with no definite volume or shape
✔ Gas
> *Explanation:* Gases are one of the four fundamental states of matter. They have no fixed shape or volume and can be compressed easily. They flow and expand to fill any container they occupy.
---
3. The theory that states that submicroscopic particles of all matter are in constant, random motion
✔ Kinetic Molecular Theory (KMT)
> *Explanation:* The Kinetic Molecular Theory explains the behavior of gases based on the motion of their particles. It assumes that gas particles are in constant, random, straight-line motion and that their collisions are elastic.
---
4. Is related to the number of gas particles and to the motion of those particles
✔ Pressure
> *Explanation:* Gas pressure results from the force exerted by gas particles colliding with the walls of their container. More particles or faster-moving particles (higher temperature) increase pressure.
---
5. An instrument that measures the pressure exerted by the atmosphere
✔ Barometer
> *Explanation:* A barometer is specifically designed to measure atmospheric pressure. The most common type uses a column of mercury, where the height of the column indicates the pressure.
---
6. The pressure exerted by the weight of the atmosphere, which at sea level has a mean value of 101,325 pascals
✔ Atmospheric Pressure
> *Explanation:* Atmospheric pressure is the force per unit area exerted by the weight of the air above us. At sea level, it’s approximately 101,325 Pa (or 1 atm).
---
7. Defined as the pressure that supports a 760 mm column of mercury
✔ Standard Atmosphere (atm)
> *Explanation:* One standard atmosphere (1 atm) is defined as the pressure that supports a 760 mm (or 76 cm) column of mercury at 0°C at sea level. It equals 101,325 pascals.
