Baseballs travel farther in high air pressure compared to low pressure.
[ ] True [ ] False

The lower the air pressure, the fewer molecules of air in any cubic foot of air.
[ ] True [ ] False

Lower air pressure also means that it is harder to breathe because of the decreased oxygen content.
[ ] True [ ] False

Sagot :

Let's address each statement one by one:

### Statement 1
Baseballs travel farther in high air pressure as compared to low pressure.
- When the air pressure is high, the density of the air is greater. This increased air density creates more air resistance or drag on the baseball. Hence, the baseball experiences greater resistance and does not travel as far.
- Conversely, in low air pressure, the air is less dense, providing less resistance, which means baseballs can travel farther.

Therefore, the statement is:
[tex]$\square$[/tex] false

### Statement 2
The lower the air pressure, the fewer molecules of air in any cubic foot of air.
- Air pressure is directly related to the number of air molecules present in a given volume. Lower air pressure means there are fewer air molecules in a specific volume.
- This results in less dense air when the air pressure is lower.

Therefore, the statement is:
[tex]$\square$[/tex] true

### Statement 3
Lower air pressure also means that it is harder to breathe because of the decreased oxygen levels.
- Lower air pressure means there are fewer air molecules in the same volume, which includes fewer oxygen molecules. This decreased oxygen availability makes it more difficult to breathe efficiently.

Therefore, the statement is:
[tex]$\square$[/tex] true

In summary:
- Baseballs travel farther in high air pressure as compared to low pressure: [tex]$\square$[/tex] false
- The lower the air pressure, the less molecules of air in any cubic foot of air: [tex]$\square$[/tex] true
- Lower air pressure also means that it is harder to breathe because of the decreased oxygen levels: [tex]$\square$[/tex] true
