Chris: Our results do not match the expected values. The boiling point we measured was three degrees higher than the textbook says. Emma: That could be due to impurities in our sample. Did we filter the solution properly? Chris: I think so, but maybe not thoroughly enough. The equipment was also quite old. Emma: We should mention that in our error analysis section. Systematic errors from outdated equipment are a valid explanation. Chris: Right. What about our hypothesis? Should we say it was partially supported? Emma: I think so. The trend was correct even if the exact numbers were off. The relationship between concentration and boiling point elevation was still visible. Chris: Good. Let me write the discussion section and you can handle the conclusion?
