Choose the pressure reference
An open manometer compares gas pressure with atmosphere, an evacuated arm gives an approximately zero reference, and a differential instrument compares two gas sources.
LIVE LAB 22 • STATES OF MATTER & GAS LAWS
Barometer & Manometer 3D Lab
Measure pressure with four 3D apparatus setups. Compare liquid levels, density, gravity and gas compression, then practise 20 questions with worked solutions.
