Hi, I want to conduct an experiment where I want to maintain water temperature at a particular value. Its an experiment for a project and I have to do it at home. Is there any ideas of how I can keep the temperature constant(may be for 45 min). I have to do the experiment at temperatures above room temperature and I have to figure out how to do it. I also dont want to increase the amount of water (like mixing in more hot water, if temperature drops) Any ideas, please help. Thanks in advance. I would be doing the experiment with 1000 ml of water.
