Question 3

(a) 1 State a suitable inference

Volume of the balloon depends on its pressure

(b) 1 State relevant hypothesis (with direction)

The smaller the pressure, the greater the volume

(c) Describe a complete and suitable experimental framework

1 State the aim of the experiment

To investigate the relationship between mass of slotted weight and

volume of gas

1 State the manipulated variable and the responding variable

Manipulated variable - mass of slotted weight, m

Responding variable - Volume of gas, V

1 State the constant variable

Constant variable cross section area, A // temperature

1 List out the important apparatus and materials

A big syringe and piston, slotted weights, rubber hose, clip and retort

stand

1 State a functional arrangement of the apparatus

Must: syringe with scale

1 State the method of controlling the manipulated variablePlace a 200 g slotted weight onto the piston

1 State the method of measuring the responding variable

Measure the volume of the gas // Record the reading of the syringe, V

1 Repeat the experiment at least 4 times with different values

Repeat the experiment for different weights, 400 g. 600 g, 800 g and

1000 g .

Question 4

Section Mark Answer

(a) 1 State a suitable inference

Brightness of the bulb depends on the length of wire

(b) 1 State relevant hypothesis (with direction)

The longer the wire, the higher the resistance

(c) Describe a complete and suitable experimental framework

1 State the aim of the experiment

To investigate the relationship between length of wire and its

resistance

1 State the manipulated variable and the responding variable

Manipulated variable : length of wire, l

Responding variable : resistance, R

1 State the constant variable

Constant variable cross section area, A // temperature

1 List out the important apparatus and materials

Constantan wire, dry cells, rheostat, voltmeter, ammeter, ruler,

connecting wires, switch and jockey

1 State a functional arrangement of the apparatus

1 State the method of controlling the manipulated variable

Turn on the switch.

Place the jockey at length of wire, l= 20.0 cm

Adjust the rheostat until the ammeter shows, I = 0.5 A

1 State the method of measuring the responding variable

Measure the potential difference, V.

Calculate resistance, R using the formula, R = V/I
