feature that circulates the heated air to heat food more quickly and evenly. In other circumstances‚ a liquid or gas can circulate on its own‚ without the help of a pump or fan‚ because of the buoyancy forces created by temperature variations within the fluid. As air is heated‚ it becomes less dense‚ and buoyancy forces cause it to rise and circulate. The rising flow of warm fluid (and the falling flow of cooler fluid to fill its place) is called natural convection. Thermals develop near mountain ridges

There are opportunities to correct for the effects of mass distribution‚ air buoyancy and damping‚ and string stretching[1]. Our results do not take these effects into account at this time. A.

non-science speak‚ this porous surface creates a lot of bubble growth sites‚ allowing the carbon dioxide bubbles to rapidly form on the surface of the Mentos. (If you use a smooth surfaced Mentos candy‚ you won’t get nearly same the reaction.) The buoyancy of the bubbles and their growth will eventually cause the bubbles to leave the nucleation site and rise to the surface of the soda. Bubbles will continue to form on the porous surface and the process will repeat‚ creating a nice‚ foamy geyser. In

induced by rotation). While all fluids behave similarly under action of forces‚ their macroscopic properties differ considerably. These properties must be known if one is to study fluid motion; the most important properties of simple fluids are the density and viscosity. Others‚ such as Prandtl number‚ specific heat‚ and surface tension affect fluid flows only under certain conditions‚ e.g. when there are large temperature differences. Fluid properties are functions of other thermodynamic variables
