Heat and Temperature of Class 7
Mercury and Alcohol Thermometer
| Advantages | Disadvantages |
| Mercury thermometer | |
| Cheap | Display is harder to read |
| Durable | Does not work below -390C (Hg freezing pount) |
| Accurate | Cannot be used for thermograph |
| Easily calibrated | Slow response |
| Fragile | |
| Mercury vapour is poisonous | |
| Alcohol thermometer (compared to a mercury thermometer) | |
| Lower freezing point (-1140C) | Less durable (alcohol evaporates) |
| Larger coefficient of expansion | Alcohol can polymerise |
| Less hazardous | Fluid loss by evaporation hard to avoid |
| Lower boi |
