DATA LOGGING
NAZURA BT YUSOFD20091035106
WHAT IS DATA LOGGING ??
Process of using computer to collect data through sensors, analyze data and save the output result of the collection and analysisData : a collection of results
Data logging : process of handling data by using computer technology.
ELEMENT OF DATA LOGGING
sensor Interface box
computer
Appropriate software
Better learning outcomes
Improve presentation of data
Save time
Increase level of interest of student
ADVANTAGES
ENDOTHERMIC AND
EXOTHERMIC PROCESS
ENGAGEEndothermic and Exothermic
reaction ?
(a) (b)
1.How the temperature or heat of the surrounding changes?
2.Which of this picture are endothermic reaction?
3.Which of this picture is exothermic reaction?
4.How water can freezing and melting?
QUESTION?
EMPOWER
sensor Data collector
Solution cooper(II) sulphateSolution anhydrous cooper(II) sulphate
Carry out experiment
result
a) Is the enthalpy change for this reaction exothermic and endothermic?
b) What sign should the enthalpy change have?
c) What is the equation for this reaction?
d) What bond are breaking broken and formed in this reaction?
e) What is this enthalpy change called?
f) How can we make at triangle between these reaction
ENHANCE
Cold packs and putting ice in towel causes a cooling effect on their person head and temporarily relieve the pain and fever. explain
Cold pack
When the cold pack is used, the chemicals inside the pack are made to react with each other and this reaction is highly endothermic in nature
Endothermic reaction involve the absorption of heat
The ammonium nitrate mixing the water creates cold.
The temperature of cold packs can reach back to normal temperature.
The heat energy is taken into the system from the surrounding. The surrounding in this case is the persons head.
CONCLUSION
