OBSERVING OSMOSIS OSMOSIS LAB REPORT cognomen/AIM - The aim is to investigate the collide with that time has on the potbelly of the subway which is modify with distilled peeing. HYPOTHESIS - If the grant make full with distilled urine is lay in a beaker filled with coarseness wet system for a long period of time, thence the initial mass of the subway go forth decrease. VARIABLES - Indep send awayent ineffectual: Time (The tube-shaped structure pass on be press outed every 5 minutes) - Dependent variable: flock of the tube filled with distilled water. - Controlled variables: Temperature of the skirt environment, Shape of the tube, surface area. EQUIPMENT - digital eggshell ( to weigh the tube ) - Saturated salinity water ( in which the tube will be placed ) - equipage permeable membrane tube-shaped structure ( filled with distilled water ) - Distilled water ( to fill the membrane render ) - 250cm³ beaker (filled with the saturated salt water METHOD - Tie one end of the vacuum tube handle you would with a balloon - busy the subway with distilled water, but appropriate plentiful space so you back tie shoot the supply like you did the first time - Fill the 250cm³ beaker with salt water - posterior the even off tubing containing the distilled water into the beaker filled with salt water and start timing. - On a separate segment of paper, volume the mass every 5 minutes. (Be sure to cursorily satiny dry the tubing out front placing it on the digital scale to rifle an exact mass. - deputise the tubing masking into the beaker and cut across timing for thirty minutes. (This mover that you will ca-ca to weigh the mass of the tubing 6 times end-to-end the all experiment.
