Ali uses two different sizes of nails to work on his Kemahiran Hidup project. He realizes that, when he uses bigger size of nails, he needs to hit the nail harder, compared when he uses smaller size of nail.

From your knowledge, what is the explanation for this situation?

Q: Compare the air pressure exerted on the 10 ml of

syringe and 20 ml of syringe.

A: The pressure exerted on 10 ml syringe is greater

than

20 ml syringe. For example, the value of pressure for

10 ml syringe at 13 s is 188.266 kPa compared to 20

ml syringe is 152.61 kPa.

DISCUSSION

Questions

QuestionsQ: Based on the results from the tables and graphs above, explain the relationship between the surface area and the pressure exerted?

A: The value of pressure (kPa) is influenced by the surface area. Smaller size of syringe (10 ml) exerts greater pressure compared to bigger size of syringe (20 ml). As a conclusion, the smaller the surface area, the greater the value of pressure exerted.
