The gas is heated to 380 K and the pressure of the gas increases to 1.9 atm. What is the volume of the gas under these new conditions?As the Kelvin temperature of gas increases by a factor of two inside a sealed rigid container,...
In the body, enzymes catalyze a variety of different types of reaction, ranging from the breakdown of proteins and peptides, to attaching active groups to molecules. Enzymes function by lowering the activation energy (the energy required to initiate the reaction) of a ...
As with a chemical or atomic reaction, the pure energy produced by the condensation process has to go somewhere. In a solid, liquid or gas this may be by conduction and convection – thermal excitation of colliding molecules, in a vacuum only electromagnetic radiation can transport energy. In ...
Provided that the electrons in the atomic case don’t “blow away” and reassociate with an adjacent nucleus, and in the molecular cases that the molecules aren’t torn apart by the force of the electric field, the material functions as an insulator; it doesn’t support a sustained flow of...
The Saudi kingdom, as it enters a period of transition, may feel more vulnerable to external threats and eager to show the world that it still has the solid of backing of the U.S.—the country the kingdom always has seen as its ultimate protector. But in the longer term, the ...
Meat and Fish:Once the excess moisture has been dabbed away, make a wash that contains reducing sugar (such as corn syrup orinvert sugar) and baking soda. Baking soda increases the pH of amino acids, making them more eager to react. Mix the two together and brush onto the meat before ...
(MSU)mounted on the satellites and monitoring microwave emissions from oxygen molecules in the atmosphere. The wavelength of these emissions are directly related to the temperature. According to the Marshall Space Flight Center which control these units, the temperature so measured is accurate to ...
Because we cannot directly watch the molecules as they react, the best we can usually do is to infer a reaction mechanism from experimental data, particularly that which relates to the rate of the reaction as it is influenced by the concentrations of the reactants. This entirely experimental ...
When you take a long hydrocarbon chain molecule from a heavy crude batch, then separate it into two smaller molecules (lighter liquid) you need a couple of hydrogen atoms to replace the C - C bond that has been broken. This hydrogen usually comes from natural gas (CH4), so refinery gains...
The key to non-stick stainless steel is to completely heat your dry pan before you add any fat…then melt fat, then add your food. It has something to do with the molecules in the steel expanding and creating a smooth cooking surface, I understand. ...
