Laboratory exercises to accompany Carhart and Chute's First principles of physics . Fig. 23. this air may be found by measuring the water which willrun into the exhausted flask.

See thatall joints between rubber and glass aretight before exhaustion. AllowT at leastfive minutes for the exhaustion of the flask, and be surethe screw compres-sor is tightly closedbefore the removalof the rubber tube from the most of the flask inwater and open the screw com-pressor a little at a time underwater. As soon as no more waterwill run in, move the flask so thatthe level of the water on the in-side is the same as that on theoutside (Fig. 24). Pinch the rubber tube withthe compressor so as to close it,and remove the flask from thewater. Set it in a secure uprightposition on the table. Op
