Answer:
As you cool a matter to absolute zero, their kinetic energy reduces significantly and the molecules slows down and begins to aggregate together. ... As heat is added, the molecules gain more kinetic energy. This shown in their increase motion. When heat is withdrawn, the particles slows down hope this helped
Answer:
It is a chemical change.
Explanation:
When the electricity is off, the filament cools down to its original physical state. This physical process repeats every time the light is turned on and off. However, if the bulb is cracked and air is introduced, the oxygen in the air reacts with the tungsten filament which then undergoes a chemical change.
By using the quantum model of the atom and John Dalton's model you can predict that the methane molecule will most likely be made up of Hydrogen and Carbon.
Answer:
Healthy kidneys clean your blood and remove extra fluid in the form of urine. They also make substances that keep your body healthy. Dialysis replaces some of these functions when your kidneys no longer work. There are two different types of dialysis - hemodialysis and peritoneal dialysis. The following is about hemodialysis.
Answer:
V = 1.84 × 10³ L
Explanation:
You need to use the Ideal Gas Law and solve for volume.
PV = nRT
V = nRT/P
First, you need to convert the pressure to atm.
1 atm = 760 mm Hg
948/760 = 1.247 atm
Next, convert grams of xenon to moles. The molar mass is 131.293 g/mol.
128/131.293 = 0.975 mol
You now have all of the values needed.
P = 1.247 atm
n = 0.975 mol
R = 8.314 J/mol*K
T = 283 K
Plug the values in and solve.
V = nRT/P
V = (0.975 × 8.314 × 283)/1.247
V = 1.84 × 10³ L
The volume of the sample will be 1.84 × 10³ L.
