Charle’s Law

Charles’s Law Apparatus is used to study that the degree of expansion was directly proportiol to the increase in temperature. This Charles’ Law Apparatus ebles students to precisely determine the volume coefficient of expansion of air throughout a temperature range. By adding or draining the acid (through a stop-clip located at the bottom of the tube), the solution in the tubes can be maintained at even levels while the temperature in the water jacket is varied. Temperature is changed by adding hot water through a funnel at the top of the jacket, as cooler water is drained from below through a rubber tube.
