Asample of glucose (c6h12o6) of mass 1.25 g is placed in a test tube of radius 1.00 cm. the bottom of the test tube is a membrane that is semipermeable to water.
the tube is partially immersed in a beaker of water at 298 k so that the bottom of the test tube is only slightly below the level of the water in the beaker.
the density of water at this temperature is 997 kg m-3.
after equilibrium is reached, how high is the water level of the water in the tube above that in the beaker?

what is the value of the osmotic pressure?

you may find the approximation ln 1/1+x \approx -x useful.

Agroup of students is studying convection currents. they fill two identical balloons with the same amount of helium. one balloon is placed in a freezer and the other in an area with warm air. after 10 minutes, the balloons are released from a height of 1 meter. which of the following do the students most likely observe? a. the balloons both rise. the cold balloon is larger than the warm balloon. b. the balloons rise at the same rate. both balloons are the same size. c. the warm balloon expands and rises. the cold balloon shrinks and sinks. d. the cold balloon expands and rises. the warm balloon shrinks and sinks.
