not to sure about matter but ill give it a try
Matter
An alchemist was someone who looked for the secret of life, in order to try and find a way of living forever. On the way to finding that they looked at whether you could change one thing into another. The most well remembered of these experiments was about whether you could change base metals (like lead) to gold.
the reason why a indicator is important in some titration is to show a change in the solution. for example as a solution runs from acidic to basic the indicator may turn a different color. but this is the reason why it is important inmost experiments.
Nobody; exothermic reactions exist independent of our will.
chemical change
Thomson's experiments with cathode ray tubes helped him to discover the electron (which Dalton did not know about). Dalton thought that atoms were in.
Chemists perform experiments to find out different kinds of matter can change.

Technically, there would just be a different result.
Chemical Change and Physical Change
Scientists record experiments in trials.They repeat experiments over and over again so they can find averages.Also,experiments in different conditions,called varibles,could change.But the main reason is the outcome would change

one
Practically all chemists are involved in the study of chemical changes.
I would hope it would only take one
Yes, it can if the experiments can add more data to make a real change. You would have to have others do the same experiments and agree with you.
To change (increase or decrease) carbon dioxide concentration and temperature (in different experiments, not simultaneously) and to measure the effect on growth.
