8. Diagram 8.1 Shows the apparatus set-up and the initial temperature reading of distilled water in an experiment. The distilled water is heated.
Record the initial temperature of the
distilled water
Diagram 8.1
Student should know how to read the reading of any measurement

State the variables involved in this experiment Table 8.1
(i) Manipulated variable - Time(ii) Responding variable – Temperature(iii) Constant variable – Type of water, volume of water,
rate of heating
Students must know WHAT YOU WANT TO CHANGE, (Manipulated)WHAT HAPPEN if you change it: (Response)What you DONT WANT TO CHANGE. (Control, Constant, Fixed)The meaning of each of these variables must be properly understood
Responding variable
Manipulated variable
(c) State a hypothesis based on the result in Table 8.1
Temperature depends on time
Hypothesis should be “derived” from the above stimulus. Acceptable answers are:-As time increases, temperature also increases orTime influence temperature
Hypothesis – Sesuatu pendapat yang dianggap benar tetapi belum dibuktikan –” I think – temperature will depend on time
Time 2 4 6 8 10
Temperature / °C 50 70 90 100 100
(d) For this part of the question, use the graph paper provided on page 21.
Time 2 4 6 8 10
Temperature / °C 50 70 90 100 100
It must be a line graph. The points should be marked properly with an X and not with a dot. The line should be curved nicely. However if the points are connected with straight line it is still accepted.
In this case the line should start at 32ºC, because the temperature of water is around 32 ºC.
Based on Table 8.1 draw a graph of temperature against time.
