CONCEPTUALISING ANSWERS SCHEME

3.
1. Apparent weight in Diagram 9.1(c) > Diagram 9.1(b) // vise versa
2. Weight lost in Diagram 9.1(b) > Diagram 9.1(c) // vise versa
3. density of water > density of oil
4. The greater the density of liquid, the greater the weight lost / less apparent weight

5.
1. Density of air in Diagram (a) is higher than in Diagram (b).// vice versa
2. The number of load in Diagram (a) is greater than in Diagram (b)// vice versa
3. The height of the balloons in both Diagram (a) and Diagram (b) are equal
4. When the density of the air increase, the buoyant force increase
5. As the density of the air increase, the weight of the load carried increased// .
As the density of the air decrease, the weight of the load carried also decreased


7.
1. Density diagram (a) <> angle of refraction in diagram (b)
4. The higher the density the smaller the angle of refraction
5. The higher the refractive index the smaller the angle of refraction.



8.
1. Refractive index digram (b) larger than diagram (a)
2. Refraction angle diagram (b) is smaller than diagram (a)
3. Critical angle diagram (a) larger than diagram (b)
4. When the refractive index is large,
5. the critical angle is small
