Understanding Pressure in Solids

What is the arrangement of particles in a solid according to the particle model?

• Random and far apart

• Far apart in a regular pattern

• Close together in a regular pattern

• Random and close together

How is pressure in solids calculated?

• Force multiplied by area

• Force divided by area

• Area divided by force

• Force plus area

What is the standard unit for measuring pressure?

• Newtons per meter squared

• Meters per newton squared

• Centimeters per newton squared

• Newtons per centimeter squared

If a person exerts a force of 500 newtons on the front of a shoe with an area of 80 cm², what is the pressure exerted?

• 6.25 newtons per centimeter squared

• 62.5 newtons per centimeter squared

• 625 newtons per centimeter squared

• 0.625 newtons per centimeter squared

Why do high heels often get stuck in soft ground?

• They are too heavy

• They distribute weight evenly

• They have a small area, increasing pressure

• They have a large area, reducing pressure

What is the pressure exerted by a heel with an area of 0.8 cm² under a force of 500 newtons?

• 6.2 newtons per centimeter squared

• 6200 newtons per centimeter squared

• 620 newtons per centimeter squared

• 62 newtons per centimeter squared

How do large flat feet help animals like polar bears walk on snow?

• They melt the snow

• They make the snow harder

• They decrease pressure on the snow

• They increase pressure on the snow

What happens to the pressure when the area is reduced, as in the case of a drawing pin?

• Pressure fluctuates

• Pressure increases

• Pressure remains the same

• Pressure decreases

If a drawing pin exerts a force of 20 newtons on an area of 1 cm², what is the pressure on the thumb?

• 0.2 newtons per centimeter squared

• 2 newtons per centimeter squared

• 20 newtons per centimeter squared

• 200 newtons per centimeter squared

What is the pressure exerted on the notice board by a drawing pin with an area of 0.008 cm² under a force of 20 newtons?

• 250 newtons per centimeter squared

• 2500 newtons per centimeter squared

• 25000 newtons per centimeter squared

• 25 newtons per centimeter squared
