Barometer was invented by _______?
Correct answer: B. Torricelli
- A. Pascal
- B. Torricelli
- C. Newton
- D. Huygen
Explanation
Evangelista Torricelli invented the mercury barometer by showing that atmospheric pressure could support a column of mercury. Pascal later used barometers to study pressure variation with height, so Pascal is the most likely mistaken choice.

About Standard Temperature and Pressure
Standard temperature and pressure provide reference conditions for gas calculations: 0°C or 273 K and, in the usual school convention, 1 atm pressure. Questions use these conditions to relate pressure, volume, temperature and amount of gas, including the molar volume of an ideal gas, about 22.4 dm³.
