review Pressure Changes

What happens to air pressure as altitude increases?

• Air pressure increases as altitude increases.

• Air pressure fluctuates randomly with altitude.

• Air pressure remains constant regardless of altitude.

• Air pressure decreases as altitude increases.

How does pressure differ between gases and liquids?

• Pressure in gases does not change with depth.

• Pressure in liquids is variable and depends on temperature and volume.

• Pressure in gases is variable and depends on volume and temperature, while in liquids, it increases with depth and is relatively constant.

• Pressure in gases is always higher than in liquids.

State Boyle's Law in your own words.

• At constant pressure, volume increases as temperature decreases.

• Pressure and volume are directly related at constant temperature.

• For a fixed amount of gas at constant temperature, pressure and volume are inversely related.

• For a fixed amount of gas, pressure remains constant regardless of volume changes.

What is the relationship between volume and pressure in gases according to Boyle's Law?

• Increasing the volume of a gas increases its pressure according to Boyle's Law.

• Pressure has no effect on the volume of a gas according to Boyle's Law.

• Volume and pressure are directly related in gases according to Boyle's Law.

• Volume and pressure are inversely related in gases according to Boyle's Law.

Explain how pressure changes can lead to weather phenomena like storms.

• Pressure changes can create low-pressure areas that lead to storms as warm air rises and cools, causing condensation and precipitation.

• High-pressure areas always lead to clear skies and no storms.

• Storms are caused solely by humidity levels, not pressure changes.

• Pressure changes only affect temperature, not weather patterns.

What is the effect of temperature on gas pressure?

• The pressure of a gas increases with an increase in temperature.

• Gas pressure remains constant regardless of temperature changes.

• Temperature has no effect on gas pressure.

• Gas pressure decreases with an increase in temperature.

How does pressure affect the boiling point of liquids?

• Higher pressure lowers the boiling point of liquids.

• Pressure has no effect on the boiling point of liquids.

• Higher pressure raises the boiling point of liquids.

• Lower pressure raises the boiling point of liquids.

What happens to the pressure of a gas when it is compressed?

• The pressure of a gas increases when it is compressed.

• The pressure of a gas becomes zero when it is compressed.

• The pressure of a gas remains constant when it is compressed.

• The pressure of a gas decreases when it is compressed.

How does altitude affect the boiling point of water?

• Higher altitude increases the boiling point of water.

• Boiling point of water is constant regardless of altitude.

• Altitude has no effect on the boiling point of water.

• Altitude decreases the boiling point of water.

What role does pressure play in the human respiratory system?

• Pressure regulates blood flow in the heart.

• Pressure has no effect on breathing patterns.

• Pressure helps in nutrient absorption in the lungs.

• Pressure changes drive the inhalation and exhalation of air in the lungs.
