What is the basic definition of pressure?

• The force applied perpendicular to the surface of an object per unit area

• The amount of space an object occupies

• The weight of an object

• The speed at which an object moves

Which instrument is commonly used to measure pressure?

• Thermometer

• Barometer

• Ruler

• Scale

In which of the following scenarios is pressure a critical factor?

• Calculating speed

• Measuring temperature

• Inflating a tire

• Boiling water

How does pressure affect the boiling point of a liquid?

• It increases the boiling point

• It has no effect on the boiling point

• It decreases the boiling point

• It changes the color of the liquid

What happens to pressure when the area over which a force is applied decreases?

• Pressure decreases

• Pressure increases

• Pressure remains the same

• Pressure becomes zero
