Somehow extract all air and place an Alka-Seltzer and water into the sealed environment. The CO2 released can be observed to see if it will enhance plant growth. 11.) Place Alka-Seltzer in a small bottle of water. Fit a balloon to the top of the bottle. The balloon will fill with “air.” 12.) Have children create their own rocket from construction paper. Affix rocket to a film canister. Place Alka-Seltzer in the film canister with water. Have children put the lid on the film canister

Two balloons are charged with an identical quantity and type of charge: -6.25 nC. They are held apart at a separation distance of 61.7 cm. Determine the magnitude of the electrical force of repulsion between them. Given: Q1 = -6.25 nC = -6.25 x 10-9 C Q2 = -6.25 nC = -6.25 x 10-9 C d = 61.7 cm = 0.617 m Find: Felect = ??? Felect = k • Q1 • Q2 / d2 Felect = (9.0 x 109 N•m2/C2) • (6.25 x 10-9 C) • (6.25 x 10-9 C) / (0.617 m)2 Felect = 9.23 x 10-7 N 3. Two balloons with

Problem: Do different conditions affect the fermentation of yeast? Variables: Controlled Variables: The yeast and water. Independent variables: Honey‚ pancake syrup‚ sugar‚ vinegar‚ salt‚ and baking soda. Dependent variable: How big the balloon becomes (filling up with CO2). Hypothesis: When yeast is mixed with more than

This proactive risk-assessment approach is used in addressing operational challenges such as operating room turn-over‚ emergency room waiting time‚ door-to-balloon time‚ etc. Hence‚ it can be asserted that FMECA procedure is an effective tool in identifying and

Drop the raisins in. Those tiny bubbles attaching themselves to the raisins are carbon dioxide (CO2) bubbles. The irregular surface of the raisins enables a lot of CO2 to accumulate. When enough gas bubbles attach to the raisins‚ they act like tiny balloons‚ giving the fruit enough lift or buoyancy to rise. The raisins should rise to the top of the glass and float on the surface. As the carbon dioxide escapes into the atmosphere‚ though‚ the raisins will sink. Then the whole process will repeat itself

ANGIOPLASTY/ BALLOON ANGIOPLASTY Coronary angioplasty is accomplished using a balloon-tipped catheter inserted through an artery in the groin or arm to enlarge a narrowing in a coronary artery. Coronary artery disease occurs when cholesterol plaque builds up (atherosclerosis) in the walls of the arteries to the heart. Angioplasty is successful in opening coronary arteries in 90% of patients. 40% of patients with successful coronary angioplasty will develop recurrent narrowing at the site of balloon inflation

Gas Laws Lab Introduction: The four basic physical properties of a gas sample are pressure‚ volume‚ temperature‚ and number of moles. The volume simply indicates the volume of the container since a gas will take up all space available to it. The temperature indicates the average kinetic energy of the gas particles. For gases‚ the temperature must be converted to the Kelvin unit. The pressure of the gas indicates the number of collisions with each other and the wall of the container. The number

Endoscopic retrograde cholangiopancreatography (ERCP) has become one of the most important techniques for the diagnosis and treatment of choledocholithiasis. Endoscopic balloon dilatation (EBD) and endoscopic sphincterotomy (ES) are the most important endoscopic techniques used for retrieval of common bile duct stones (1) and ES is the most commonly used method as a standard technique. (2) Despite the relative safety of ES the overall complication rate is about 10%. (3) The short-term risk of pancreatitis

cut it all out we decided to cut out pieces of cardboard the same shape and put it behind the paper so it was more stable and added some weight. For our balloon‚ we put a hole in the back of the car that we could put a straw through‚ and taped the balloon to the straw. We taped the straw up on the back part of the car so when we blew up the balloon it would go straight up. Our wheel idea came to mind when I was drawing out an idea for our car. I was using a blue highlighter‚ accidentally dropped
