Hello, this is about a science question. Please help. 

I am practicing some questions for my science. One question is about the resolution of my measuring instrument which is 1 degrees C. 

Another question is, was the resolution appropriate for your investigation? How do I answer this? What sort of things do I mention?

Talk about percentage uncertainties and how it is difficult to tell from a thermometer if there are 0.1 degrees etc

What i mean to say is that if for the purpose of you experiment measuring to 1 degrees was ok then you say it is and you say why!! but most likely not because at 1 degrees resolution, it is not precise enough especially if you are measuring a quantity and the marker falls in between two values which are not equidistant, meaning you kinda have to guess what it is or round up making your results less accurate etc etc

Thank-you that was very helpful! However, on the question mark scheme, it says mentioning the work 'accurate' shows lack of understanding of the word resolution?
