Homework Statement Heat is added until the rms speed of a helium atom has increased 50%. Find new pressure. (Not all parameters given.) Homework...
The rms speed depends only on the velocity distribution of the molecules. Your mistake seems to be that you're calculating the total internal energy of the gas, but is supposed to be the average kinetic energy of a single molecule. Jun 9, 2015 #5 Qwurty2.0 18 0 My bad, I ...
In mitochondria, pyruvate is oxidized to acetyl-CoA, and controlled "combustion" generates energy equivalent to two ATP molecules. The overall sum of the citric acid cycle can be represented as:Acetyl-CoA + 3 NAD+ + FAD + GDP + Pi + 2 H2O → CoA-SH + 3 NADH + 3 H+ + FADH2 + ...
The same intuition is applied to other materials science use cases with features that are long in one or two dimensions; for example, delamination in carbon fiber composites, pore space in gas-bearing shale, thin films in power structures, layer-wise metrology of semicondu...
While you can't mix pee and bleach, there is a way to deal with the situation when your whole house smells like dog urine. There are a lot of commercially available options marketed as enzymatic cleaners. These products contain enzymes, which are biological molecules that break down compounds...

The thermosphere is characterized by extremely thin air, with gas molecules spread so far apart that they rarely collide. Despite the sparse atmosphere, temperatures in this layer can soar to as high as 4,500 degrees Fahrenheit. This intense heat is primarily due to the absorption of high-energ...
The hydrogen storage tanks store compressed hydrogen gas, which is supplied to the fuel cell stack. When the driver starts the bus, the hydrogen stored in the tanks is supplied to the fuel cell stack. Hydrogen molecules then enter the anode side of the fuel cell, where they are separated ...
Of all the sciences, physics is unique in that it can come to a broad consensus with math alone—very little tactile evidence required. Never has this been the case more than with dark matter. Though it's far more abundant than thematterwe can see and feel, dark matter as we know it...
