The correct answer is A. cloud of gases that forms around the nucleus of a comet is called a coma. The coma is a dusty, fuzzy cloud around the nucleus of a comet. Other parts of a comet are the nucleus and the tail.
The pressure of the CO₂ = 0.995 atm

The complete question
<em>A student is doing experiments with CO2(g). Originally, a sample of gas is in a rigid container at 299K and 0.70 atm. The student increases the temperature of the CO2(g) in the container to 425K.</em>
<em>Calculate the pressure of the CO₂ (g) in the container at 425 K.</em>

Gay Lussac's Law
When the volume is not changed, the gas pressure is proportional to its absolute temperature

P₁=0.7 atm
T₁=299 K
T₂=425 K

Answer:
The correct answer is from areas of high concentration to low concentration.
Explanation:
A concentration gradient exists for these molecules, so they have the potential to diffuse into (or out of) the cell by moving down it.

Answer:
The London dispersion force is the weakest intermolecular force. The London dispersion force is a temporary attractive force that results when the electrons in two adjacent atoms occupy positions that make the atoms form temporary dipoles.
