Mercury is a liquid over a wide range of temperature ( -39 to 357 degrees ) so it can be used in a variety of temperature ranges. Secondly it does not stick to the glass tubing of the thermometer so when the temperature falls ( i.e. after the reading is taken) all the mercury falls back into the reservoir. This ensures the accuracy of the mercury thermometer.

Why is mercury used in thermometres?
Mercury thermometres aren't used much, because the mercury inside is poisones, But the reason that mercury used to be used is because Mercury expands rapidly, conserning the temperature e.g. if it gets hotter, the Mercury expands, so there is more of it. So, when you're measuring the tempurature, you're actually measuring how much mercury is there, therefore telling you what the temperature.
