4) Ask for assent of the child participating in the research
The above APA suggestions where not met by the researcher in the study.
When there is a temperature difference/Gradient, heat flows from a region of high concentration to region of low concentration.
<h3>Energy and Heat/Mass Transfer</h3>
Thermal energy flow from region of higher temperature gradient to region of low temperature gradient till equilibrium is reached.
When the hot metal is places in a cold water bath, there will be a temperature difference and by conduction(water conducts heat) the heat will travel in the water medium and circulate till equilibrium

Answer:
For example, one method for estimating the length of time it takes something to occur is to time it once using a stopwatch. You can reduce the uncertainty in this estimate by repeating the measurement and taking the average.
There are a lot of way to reduce the uncertainty however with real life sciences like quantum mechanics it will reveal more about the world and life if we have better measuring tools. Being precise is essential to understanding many parts of life.
Hope this helped! Have a great day!!!
