14. 14. SET 2 QUESTION 1 a) b) c) d) 2 a) b) c) d) 3 a) b) c) d) 4 a) b) c) d) ANSWER To find out the relationship between the time and the temperature of liquid X. Increase If the time taken increase, the temperature of liquid X increase. As the time taken increase, the temperature of liquid X increase. To find out the relationship between the distance of ball from light source and the size of the shadow. Decrease The longer the distance of ball from light source, the smaller the size of shadow. If the distances of ball from the light source increases, the sizes of shadow decrease. To study the relationship between the size of moon and the weight of squid caught. Increase The bigger the size of moon, the more weight of squid caught. If the sizes of moon increase, the weight of squid caught increase. To investigate the relationship between the amount of water sprinkled and the sizes of black patches. Increase The more amount of water sprinkle, the bigger the size of black patches. If the amounts of water sprinkled increase, the size of black patches increase.
