Question

In the specific heat experiment, critical factors are the heat capacity of the calorimeter, the temperature of the holt sample, and the final temperature of the calorimeter. What effect could influence the temperature of the hot sample at the instant it is inserted into the calorimeter? What issues surround the measurement of the final calorimeter temperature?

Answer 1

1) AT THE VERY INSTANT WHEN THE HOT SAMPLE IS INSERTED INTO THE CALORIMETER AN EXOTHERMC REACTION TAKES PLACE AND THE SOLUTION OF THE CALORIMETER ABSORBS THE HEAT , THERBY SHOWING A INCREASE IN TEMPERATURE . THIS CAN ALSO BE EXPLAINED AS THE FOLLOWING , SUPPOSE THE SAMPLE IS VERY HOT , THUS THE KINETIC ENERGY OF THE MOLECULES OF THE SAMPLE IS VERY HIGH AND THUS AS SOON AS IT COMES IN CONTACT WITH CALORIMETER FLUID THE MOLECULES COLLIDES WITH THE CALORIMETER (SOLUTION/ CONTAINER WALLS) MOLECULES AND TRANSFER OF MOMENTUM TAKES PLACE WHICH IS INTERPRETED AS HEAT TRANSFER .

2) THERE ARE SEVERAL ISSUES THAT SURROUND THE MEASUREMENT OF THE FINAL TEMPERATURE

OF THE CALORIMETER , MOST IMPORTANTLY IT SHOULD BE MEASURED AND NOTICED FROM TIME TO TIME THAT HOW HOT ARE THE SURROUNDINGS OF THE CALORIMETER AND THE TEMPERATURE AND COORESPONDINGLY THE HEAT TRANSFER FROM THE SURROUNDINGS TO THE CALORIMETER SHOULD BE NOTED .
