ohh ya!!
i got one i guess i guess |AM| might remeber covering it wid lid and lagging and all those stuff in specific heat capacity qus!!
thats for physics..
insulation for chem..only exo. and endo. reactions..
for e.g
Devise an experiment to show that CaO + H2O is an exo. reaction
here..u add known amount of CaO to known volume of water. record the time and temperature using thermometer.stop the watch when temp. reaches a constant value.
here..the improvememnts can be.
-Use data logging
-Use insulation
