The thermometer in the flask can be used to demonstrate the relationship between heat transfer and kinetic energy by measuring the difference in temperature at intervals.
This is defined as the degree of hotness or coldness of a substance and is usually measured with the use of a thermometer.
Heat transfer makes it possible for the temperature to be uniform by the gain and loss of heat energy by the objects present in the flask.
When this occurs, the kinetic energy also experiences a reduction which is therefore the way in which a thermometer will demonstrate the relationship between heat transfer and kinetic energy.
