Pressure is measured in Pascals. To calculate the area a force acts on to produce a pressure, you need to use the following equation: area = force/pressure.

See how well you do in our second Science quiz on the subject.......no pressure!

1.

Camels have big feet so they don't sink into soft sand because .......

they have a large area so the pressure is large

they have a large area so the pressure is small

they have a small area so the pressure is large

they have a small area so the pressure is small

2.

A skier weighs 600N, lifts one ski up and exerts a pressure of 5,000Pa on the snow. What is the area of one of the skis?

0.12m^{2}

0.24m^{2}

0.48m^{2}

1.2m^{2}

Area = 600/5,000

3.

A student weighs 500N, standing on two feet she exerts a pressure of 25,000Pa on the ground. What is the area of one foot?

50cm^{2}

0.005m^{2}

0.01m^{2}

0.02m^{2}

Area = 500/25,000 = 0.02 (two feet), one foot = 0.01m^{2}

4.

A box weighs 100N. It exerts a pressure of 25Pa on a table. What is the area of the box in contact with the table?

4mm^{2}

4cm^{2}

4m^{2}

4km^{2}

Area = force/pressure = 100/25. Remember weight is a force

5.

A box weighs 20N. It exerts a pressure of 2Pa on a table. What is the area of the box in contact with the table?

10cm^{2}

0.1m^{2}

10m^{2}

40m^{2}

Area = force/pressure = 20/2 = 10m^{2}

6.

A 60,000N elephant can stand on one foot! The pressure it exerts is 240,000Pa. What is the area of its foot?

0.16m^{2}

0.24m^{2}

0.25m^{2}

4m^{2}

Area = 60,000/240,000

7.

One box weighing 60N is put on top of one weighing 120N. The pressure they exert is 180Pa. What is the area touching the ground?

0.67m^{2}

1m^{2}

2m^{2}

3m^{2}

Area = (60 + 120)/180

8.

A sharp knife cuts well because .......

it has a large area so pressure is large

it has a large area so pressure is small

it has a small area so pressure is large

it has a small area so pressure is small

9.

Doubling the force and doubling the pressure mean .......

that area doubles

that area gets larger

that area gets smaller

that area stays the same

10.

A skier weighs 600N and exerts a pressure of 2,500Pa on the snow. What is the area of the skis?

0.12m^{2}

0.24m^{2}

1.2m^{2}

4.2m^{2}

Area = 600/2,500 = 0.24m^{2}
