The correct answer is 4. thermal energy because it is concerned with heat. When heat is increased, atoms and molecules in the air will move faster.
Hope this helps~

As the temperature is increased how does the substance move?
Karo-lina-s [1.5K]

Answer:

The movement of substances may occur across a semi‐permeable membrane (such as the plasma membrane). A semi‐permeable membrane allows some substances to pass through, but not others.

Solutions can only be separated by using distillation not filtration. Why can't a solution be filtered? Explain using the terms
garri49 [273]
<h2>Solutions</h2>

Explanation:

  • Solutions are formed when a solute gets dissolved in a solvent. The solid that gets dissolved is called solute whereas the liquid in which the solid gets dissolved is called the solvent. On dissolving,  the particles of the solute  gets incorporated between the inter-particle space of the solvent. This means that there is no significant difference between the particle size of solute and solvent. However the boiling points of solutions can differ significantly. This is the reason, the solutions cannot be separated by the method of filtration but by the method of distillation.

500 mL of water is added to 400 mL of 0.35 M HCl. Find the concentration of the diluted solution.
jarptica [38.1K]

The concentration of diluted solution is 0.16 M

<u>Explanation:</u>

As, the number of moles of diluted solution and concentrated solution will be same.

So, the equation used to calculate concentration will be:

M_1V_1=M_2V_2

where,

M_1\text{ and }V_1 are the molarity and volume of the concentrated HCl solution

M_2\text{ and }V_2 are the molarity and volume of diluted HCl solution

We are given:

M_1=0.35M\\V_1=400mL\\M_2=?M\\V_2=(500+400)mL=900mL

Putting values in above equation, we get:

0.35\times 400=M_2\times 900\\\\M_2=\frac{0.35\times 400}{900}=0.16M

Hence, the concentration of diluted solution is 0.16 M
