Answer: colloid
Explanation:
Colloids are solutions in which small sized particles are suspended throughout the solution as they do not settle own their own. Colloids are defined as the mixtures where the size of the particle is within the range of 2nm to 1000 nm. In these mixtures, physical boundary is seen between the dispersed phase and dispersed medium.
Colloids are solutions with particle size intermediate between true solutions and suspensions. Suspensions have large sized particles which settle when left undisturbed for sometime and thus can be filtered off easily. The particle size in colloids is less and hence they do not settle under the effect of gravity.
Answer:
Systems of measurement in use include the International System of Units (SI), the modern form of the metric system, the imperial system, and United States customary units.
Answer:
The volume of a 76.52 g sample of methane gas is
32.7 L at 26.9 °C and 4.45 atm. What will its volume be at 95.4 °C and 1.7 atm?
The final temperature : 317 °C
<h3>Further explanation</h3>
Given
V₁=2.5 L
V₂ = 5 L
T₁ = 22 + 273 = 295 K
Required
The temperature, T₂
Solution
Charles's Law
When the gas pressure is kept constant, the gas volume is proportional to the temperature
Input the value :
T₂ = (T₁ x V₂) : V₁
T₂ = (295 x 5) : 2.5
T₂ = 590 K = 317 °C
Answer:
Boiling points
Liquid to gas
Explanation:
For distillation, the differences in boiling points of the liquids in the column is utilized for this separation.
The change in matter involved a state change of liquid to vapor or gaseous form.
- Distillation is used to separate different liquids in a mixture.
- A liquid - liquid mixture is separated into components due to their appreciable boiling point differences.
- The method is used for purifying liquids.
- The solution is boiled in a distillation flask to vaporization.
