A sample of nitrogen gas occupies 1.83 L at 27 °C and 1.000 atm of pressure. What will
neonofarm [45]

Answer:

1.06L = V₂

Explanation:

Charle's Law states that the volume of a gas is directly proportional to the absolute temperature when pressure remains constant.

The equation is:

V₁T₂ = V₂T₁

<em>Where V is volume and T absolute temperature of 1, initial state and 2, final state of the gas.</em>

V₁ = 1.83L

T₂ = -100°C + 273.15 = 173.15K

V₂ = ?

T₁ = 27°C + 273.15 = 300.15K

V₁T₂ = V₂T₁

1.83L*173.15K = V₂*300.15K

<h3>1.06L = V₂</h3>

if the solvent-solute interactions are weaker than the average of the solvent-solvent and solute-solute interactions, then heat
Alex777 [14]

If the solvent-solute interactions are weaker than the average of the solvent-solvent and solute-solute interactions, then heat is absorbed from the surroundings and the overall mixing process is said to be endothermic process.

The endothermic process can be defined as the process in which the reactants the will absorbed the heat from the surroundings . the heat is gained from the surrounding in the endothermic process and the surroundings temperature will decreases.

The solvent - solute interaction < solute - solvent interaction \and the solute solute interaction then the solution may be or may not be formed.

Thus, then heat is absorbed from the surroundings and the overall mixing process is called as endothermic process.
