Smoke is a Mixture of Particles Suspended in the Air 
By: Alzahraa Alrubaiey 
A suspension is a mixture between a liquid and particles of solid. A suspension is a heterogenous mixture. When particles are big enough to eventually settle, they are called suspension. But if the particles are too small to ever settle, they are said to form a colloid. So, a colloid is a mixture in which one substance of microscopically dispersed insoluble particles is suspended throughout another substance. Colloid is homogenous mixtures, while a suspension is a heterogenous mixture.                                         
Smoke is a suspension in air of small particles resulting from incomplete combustion of a fuel. The particles in a suspension are far larger than those of a solution, so gravity is able to pull them down. A suspension is a heterogeneous mixture in which the solute particles do not dissolve, but get suspended throughout the air of the solvent, left floating around freely in the medium. That’s why smoke is a mixture of particles suspended in the air. Because when the smoke is released in the air it gets suspended throughout the solvent. 
Smoke is a collection of tiny solid, liquid and gas particles. Although smoke can contain hundreds of different chemicals and fumes, visible smoke is mostly carbon. Each particle is too small to see with your eyes, but when they come together, you see them as smoke. Smoke is a collection of tiny unburned particles. Smoke can often cause more damage to a building than flames or the heat of the fire.  
Smoke can cause some serious effects on the body. With increased oxygen, these can ignite either through open flames or by their own temperature. This leads to a back draught or flashover effect. In the future scientists can use other types of mixtures to prevent this. They might also change the way people escape during a fire. Because when people get exposed to smoke they might die.

Mahar-ullah Shahminah- Molecular Gastronomy

Molecular Gastronomy   By: Shahminah Mahar-ullah Date:3/22/19 Molecular Gastronomy is both a fusion of science and cooking. The scientific discipline gives the chef complete control of what the texture, taste, and physical appearance of the dish. Molecular Gastronomy is a modern unique style of cooking that some would say it could be considered art. There are three aspects of Molecular Gastronomy, as i said before it is texture,taste,and physical appearance. Molecular Gastronomy can have a very simple and familiar taste or a new and unique taste. Taste is often a aspect that is forgotten about in Molecular Gastronomy. Mostly because people who don't know much about the style of cooking kinda forget that its actually cooking ,not just some form a science. Taste is the main focus with cooking in general and with molecular cooking taste can be brought to a whole new level since you have complete control over each part of the dish. Same goes for physical appearance and ...

Chemically termolecular reactions: The fourth class of chemical reactions

Chemically termolecular reactions: The fourth class of chemical reactions Maisy Chase Up until now only three classes of chemical reactions were known. Unimolecular reactions occur when one reactant undergoes bond breaking or forming to create different products. Bimolecular reactions are where two reactants collide and then undergo bond breaking or forming. Termolecular association reactions, where two reactants collide to form a whole with a new chemical bond between the two reactants. A third molecule, known as the bath gas, then removes some of the internal kinetic energy of that molecule to stabilize it. Researchers from Columbia University , led by Assistant Professor of Mechanical Engineering Michael P. Burke, have discovered a fourth class of chemical reaction known as “chemically termolecular reactions.” This involves the breaking and bonding of three molecules. The team showed that these chemically termolecular reactions not only are major chemical pathways but also ...

Force and Motion

Zach Fluck Science blog Force and Motion Blog Sir Isaac Newton was an English astronomer, physicist, and mathematician, born on December 25, 1642. He died on March 20, 1727, most likely from mercury poisoning or old age. However, during his life, he made several contributions to modern science and advanced our understanding of physics tremendously. Arguably his most famous discovery was gravity. However, he had to use his 3 laws of motion to make this accomplishment. Newton understood that an object at rest will stay at rest, unless acted on by unbalanced forces. Therefore, if an object such as an apple is in a resting position there must be a force to make the apple fall to the ground. He discovered this invisible force to be gravity. At a young age Newton was removed from school to be a farmhand. Despite returning to school the turning point in his live was he left his hometown to attend Cambridge University. After attending Cambridge he returned to his hometown where his observat...
