Last period of the day was physics. Had practical lesson on cooling effect of salt. Nice! The nicest experiment I've so far.
It's much much better than the previous one on cooling curve because the cooling effect of salt doesn't need to use bunsen burner.
Just have to measure the salt(sodium thiosulphate) on the electronic balance, add the salt into copper calorimeter,keep stirring and observe the temperature on the mercury thermometer. Repeat the steps,each time keep adding more salt.I think the whole process of this was fun! :D
After physics,our results were out. Scored 30/40 which I'm surprised :)
It's better than chemistry which I got 23/40.
Still don't know the results for total marks for both yet because still need to plus other tests.
English test will be released tomorrow.. Will be scoring very badly for it as I did not complete the composition and did not mention the main points due to insufficient time ):
Headed back home to bathe then sleep till 7.30pm.
It's 1am now! I planned to sleep at 12am but computer distracts me.
Okay, off to sleeeeep.
Gd'night world!
