1)explain why a laboratory thermometer is not suitable for measuring human body temperature
2)why does the Mercury level not fall on its own when the bulb of a clinical thermometer is removed from the mouth
3)give one example where heat is transferred by the process of conduction

1: because the range varies in laboratory thermometer and clinical thermometer and it also do not have a kink so the mercury will fall
2: because it contains a kink which do not allow mercury level to fall down easily
3:when heat transfers from a hot pan to its handle,it is through the process of conduction
4:good conductors are meant by things which easily allow the heat to pass from it

Frnd,
Answers to ur questions are as follows:
1) WHY A LABORATORY THERMOMETER IS NOT SUITABLE FOR MEASURING HUMAN BODY TEMPERATURE?-
A thermometer used to measure body temperature is extremely accurate over an extremely small range of temperatures. It will give the temperature to the tenth of a degree. A laboratory thermometer does not have the partial degree separations but gives the temperature over a much wider range of temperatures.
2) WHY DOES MERCURY DOES NOT FALL ON ITS OWN WHEN THE BULB OF CLINICAL THERMOMETER IS REMOVED FROM MOUTH?-
A clinical thermometer measures the max temp of the human body due to the expansion of the mercury in the bulb, which flows past a kink in the column and rises in the graduated stem, to read the highest body temperature. Once it is removed from the body, the mercury stays at that level, and does not fall because it cannot flow back into the bulb (the kink prevents the back flow).
3) EXAMPLE OF HEAT TRANSFERRED BY THE PROCESS OF CONDUCTION (HEAT CONDUCTION)-
Heat conduction, also known as thermal conduction, is the process where heat is transferred within a body due to the collision of neighboring particles.
Eg.
A cube of ice is placed into the hand of a man. Over time, heat conducted from the man’s hand to the ice cube will cause the ice to melt.
4) WHAT IS MEANT BY GOOD CONDUCTORS OF HEAT?-
Good conductors are materials that can conduct electricity and heat efficiently. Most good conductors are metals but carbon (a non-metal element) also conducts electricity (pencil lead electrical switch experiment).
Hope it helped
