3.) The warmer the molecules are the faster they move like boiling water the gases are coming out of the water
4.)no clue
5.) A {solution} is always transparent, light passes through with no scattering from solute particles which are the molecule in size. The solution is homogeneous and does not settle out. A solution cannot be filtered but can be separated using the process of distillation.

A {suspension} is cloudy and heterogeneous. The particles are larger than 10,000 Angstroms which allows them to be filtered. If a suspension is allowed to stand the particles will separate out.

<span>A {colloid} is intermediate between a solution and a suspension. While a suspension will separate out a colloid will not. Colloids can be distinguished from solutions using the Tyndall effect. Light passing through a colloidal dispersion, such as smoky or foggy air, will be reflected by the larger particles and the light beam will be visible. A hydrocolloid can simply be defined as a substance that forms a gel when it comes in contact with water. Such substances include both polysaccharides and proteins.
6.)</span><span>The random movement of microscopic particles suspended in a liquid or gas, caused by collisions with molecules of the surrounding medium. Also called Brownian motion, molecular movement, pedesis.

The specific heat of a certain type of metal is 0.128 J / (g ⋅ ∘ C). What is the final temperature if 305 J of heat is added to
Arte-miy333 [17]

Answer:

Final T° is 45.5°C

Explanation:

Formula for calorimetry is:

Q = m . C .  ΔT , where

ΔT = Final T° - Initial T°

C = Specific heat

m = mass

Let's replace with the data given

305 J = 93.4 g . 0.128 J/g°C . (Final T° - 20°C)

305 J / 93.4 g . 0.128 J/g°C  = Final T° - 20°C

25.5°C = Final T° - 20°C → Final T° = 25.5°C + 20°C = 45.5°C
