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!

Science: Middle School: Grades 6, 7 and 8 Quiz - Pressure 2 (Answers)
1. 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?
[ ] 4mm2
[ ] 4cm2
[x] 4m2
[ ] 4km2
Area = force/pressure = 100/25. Remember weight is a force
2. 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?
[ ] 10cm2
[ ] 0.1m2
[x] 10m2
[ ] 40m2
Area = force/pressure = 20/2 = 10m2
3. A skier weighs 600N and exerts a pressure of 2,500Pa on the snow. What is the area of the skis?
[ ] 0.12m2
[x] 0.24m2
[ ] 1.2m2
[ ] 4.2m2
Area = 600/2,500 = 0.24m2
4. 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?
[x] 0.12m2
[ ] 0.24m2
[ ] 0.48m2
[ ] 1.2m2
Area = 600/5,000
5. 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?
[ ] 50cm2
[ ] 0.005m2
[x] 0.01m2
[ ] 0.02m2
Area = 500/25,000 = 0.02 (two feet), one foot = 0.01m2
6. 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?
[ ] 0.67m2
[x] 1m2
[ ] 2m2
[ ] 3m2
Area = (60 + 120)/180
7. A 60,000N elephant can stand on one foot! The pressure it exerts is 240,000Pa. What is the area of its foot?
[ ] 0.16m2
[ ] 0.24m2
[x] 0.25m2
[ ] 4m2
Area = 60,000/240,000
8. Camels have big feet so they don't sink into soft sand because .......
[ ] they have a large area so the pressure is large
[x] 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
