| Usage notes | Use 'heat' when talking about temperature or warmth. It's neutral and appropriate in scientific discussions as well as casual conversations. Avoid using it in overly formal contexts like academic papers. | Used in both casual and formal contexts, 'temperature' is appropriate for discussions about weather, science, and health. Avoid in very informal conversations where simpler terms like 'hotness' or 'coldness' might be used. | Use 'warm' to describe temperature in both physical and emotional contexts. It's applicable in casual conversations, but for formal writing, you might use 'mild' when referring to climate. |
