Answer:
Transduction
Explanation:
Transduction is a reasoning in which a person co-relate two different situations. In this, the person relates two situations and marks them the same due to the impression of older observation even though they can be related and unrelated.
So here the 4-year-old girl is showing transduction because earlier that nurse wearing shirts with flowers gave shots to the girl so now when she sees that nurse again she relates this situation to the earlier one and starts crying.
So the statement "Nurses who wear shirts with flowers give shots" shows that this is an example of transduction.
<span>The usual answer (and correct) is to improve on the insulation, for example by covering the calorimeter, and using two cups, one inside the other.
Further improvements can be made
1) carrying out the experiment over as short a period of time as possible. reason; any calorimeter will loose heat, but the shorter the time allowed, the less heat will be lost.
2) Use a larger calorimeter, with greater volume of solution. reason; the greater the solvent mass requires more energy to obtain the same change in temperature. You get a smaller temp change for the same reaction, so less losses to the surroundings.
3) calibrate your calorimeter heat the same volume of pure water to a similar temperature as that which the reaction produces. Then determine the rate of heat loss over a period of time, say take temp every minute for 30 minutes, and plot a graph. This will give you a calibration curve that you can use to apply a correction for your calorimeter.</span>
