Description

Science First Absolute Zero Device is used to display the relationship of pressure to temperature of a gas. Device enables students to experimentally decide absolute zero. Soak the bulb in hot water, cold water and a dry ice or alcohol mixture to show successive drop in pressure. Then plot standard readings to attain an absolute temperature scale. Device contains a valve fitting for attachment to an air pump.
Please Note:
This unit includes a lead-free gauge with a scale from 0 to 30psi. A bicycle pump can be used to increase the internal pressure to 15 psi thus allowing for increasing and decreasing pressures based on temperature.
