Go Direct® Gas Pressure Sensor

Gas Pressure and Volume Demonstration

Matter

Demonstrate that gas occupies space and exerts pressure — air trapped in inverted glass experiment from textbook

Gas Pressure Demonstrates Gas Properties

States of Matter

Measure gas pressure in sealed container — directly demonstrates gas fills space, exerts pressure, is compressible

Gas Pressure During State Change

Arrangement of Atoms/Molecules in Solids, Liquids and Gases

Measure gas pressure increase as liquid evaporates in sealed container — supports evaporation/gas concepts

Gas Laws and Pressure

Matter and its Composition

Measure gas pressure change with temperature; demonstrates kinetic theory and intermolecular spacing in gases

Gas Evolution Detection

Chemical Reaction and Chemical Equation

Detect CO2 from Na2CO3 + HCl reaction as described in textbook; measure pressure increase from gas evolution
