5965 Apparatus to show the uniform behaviour of simple and compound gases under variations 



of temperature and pressure 



Consists of U tube with stopcock at foot, one limb of which branches into two, with stopcocks, which are 

 also surrounded with a glass tube into which water of varying temperatures can be poured. The apparatus is 

 first filled with mercury, and then two gases are admitted into the branch tubes, and subjected to various tempera- 

 tures and pressures, when they will be found to remain the same in volume.
