You can use a mercury thermometer to accurately infer whether mercury expands linearly with temperature
Open in App
Solution
The correct option is B False
No! You cannot use the thermometer to verify the linear expansion of mercury. This is because the temperature scale itself is defined by making equal markings between 00 C and 1000 C, assuming that mercury expands linearly.
In fact, scientists have now established using statistical physics and other concepts that mercury does not expand exactly in a linear fashion.
Before all this, the only way to guess if a thermometer fluid is a good choice (i.e, expands linearly) was to observe which of them gave consistent results.
