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.

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.
