How to calculate the reading of a mercury barometer
Answers
Answer:
Take the reading at the top. Slide the vernier above the top of the mercury column. Then slowly lower it until the bottom edge of the vernier is parallel with the top of the mercury meniscus. Read the fixed scale to one side of the mercury to get the whole number value - in this case 766 mm.

Answer:
volume one litre at 0°C is filled, level full of mercury at this
temperature. The flask and mercury are now heated to 100°C. How much
mercury will spill out if coefficient of volume expansion of mercury is 1.82
