RVFM Boyle's Law Apparatus

This apparatus is designed to demonstrate Boyle's Law to the whole class.

• Wide bore glass tube mounted vertically in front of a scale graduated 0 to 60cm
• Zero corresponds to the inside of the closed (top) end of the tube
• Air is confined in the tube by a coloured oil contained in a metal pressure chamber
• Pressure chamber is fitted with a Bourdon type gauge calibrated 0 to 3.5kg cm² (0 to 50 lb/in²) actual pressure
• A valve is fitted to the air inlet tube from the pump
• As the pressure in the oil chamber is increased, oil level and its actual (total) pressure are directly indicated
• Tube is made of extra strong glass and is securely covered with transparent plastic on the front
• Overall height of apparatus approx. 690mm
• Suitable for Key Stages 3 & 4 (ages 11 to 16)
