early 1950 ’s a time of technological growth were speed was considered high priority and was evidence of stronger economy. The belief was that Supersonic aircraft would replace all other aircraft what would eventually become known as a supersonic transport (SST). In aviation‚ high-speed and altitude where the most desired progress where faster and higher was better. Research and design studies into supersonic flight at the Royal Aircraft Establishment (RAE)‚ and comparable projects in France undertook

Question 1: How does Osmosis works It refers to the movement of water molecules from an area of high-level water concentration‚ that is‚ a dilute solution‚ to an area of low-level water concentration‚ that is‚ a strong solution through a semi-permeable membrane. (Passmyexams.co.uk‚ 2015) Actually‚ water moves in a bi-directional manner with the aim of leveling up the concentration. However‚ a high number of water molecules move from the fresh water towards the salty water. The outcome

partially supported because glucose left the bag and is proven by the positive test on the surrounding water. Also the beaker turned orange because of osmosis which attests to glucose leaving the bag. Iodine Potassium Iodine and water entered the bag. This was proven by the color change in the starch test as the bag turned black also because of osmosis. The only thing that the hypothesis lacked was that starch did not move at all. The beaker stayed yellow before and after because the bag is not permeable

Air Pressure Air is composed of molecules. Air is matter. It has mass and takes up space. Air is composed of different gases such as nitrogen‚ oxygen‚ carbon dioxide‚ water vapor‚ and other gases. Air molecules are in constant motion. As they move‚ they come in contact with surfaces. Air molecules push and press on the surfaces they contact. The amount of force per unit area that air molecules exert on a surface is called air pressure. (What is Air Pressure 6) Air pressure is caused by all
