Choose the correct statement for this question: If two objects have different temperatures, in which direction will heat move? For how long? 1. Heat moves from hot to cold objects/areas, and it never stops.
2. Heat moves from cold to hot object/areas.
3.Heat moves from hot objects/areas to cold areas and stops moving once it reaches a thermal equilibrium.

The independent is what is changed, the dependent is was is measured or the reaction.

In order to improve results, many different steps can be taken into account. 1) using more precise scales and thermometers is always something that should be considered as being precise means that you are more exact with your answer.2) increasing the sample size should also be considered, if you have a bigger sample size you are able to determine if your results are accurate as well as if there are any variables that should be taken into account plus it assists in the statistical analysis and produces overall better data3) using better handwriting is also a plus, along with organizing the data properly so that others are also able to read the results and even redo the experiment in the future if it is needed.
