Temperature has a clear effect on the growth rate of salt crystals. If you carry out an experiment with salt solutions, one at room temperature, one at a colder temperature and one at a warmer temperature, you see that the warm temperature sample grows crystals faster than both the other samples, and the room temperature sample grows faster than the cold sample. This is because a higher temperature increases the rate of evaporation of the solvent, thereby speeding up the rate of growth. Different temperatures produce different amounts of crystals. Colder solutions contract, forcing minerals closer together, so they create bonds, catching impurities in their structure at the same time. These impurities interrupt the crystal pattern, forming a larger number of smaller crystals. In warmer temperatures, the distance between molecules is greater, which allows crystals to form larger, purer shapes at a much more uniform rate than can occur at colder temperatures.
Answer:
The answer to your question is below
Explanation:
There are 4 laws of gases
- Charles
- Gay Lussac
- Boyle - Mariotte
P1V1 = P2V2
- General law of gases
Let's use these formulas to answer the question
p2 = V2/P1 This is not a law of gases
p1= V1/k This formula is similar to Boyle mariotte equation
but is not.
V2 = k/P2 This equation is correct is Boyle Mariotte formula
V2 = P1V1/ P2 This equation is also correct is Boyle Mariotte formula
V1 = P1/P2 (V2) This equation is incorrect
P2 = (P1) V1/V2 This equation is correct is Boyle mariotte formula
<span>Condensation takes place when gas molecules lose heat and kinetic energy. The warmer molecules are the faster they move. Gas molecules move very quickly and have a lot of kinetic energy and heat energy. As the gas molecules lose heat they also lose kinetic energy. As the molecules slow down they move closer together to form liquids.</span>
To answer this question a balanced chemical equation is necessary. The correct equation is: N2 + 3H2 = 2NH3
From this equation, one mole of nitrogen react with 3 moles of hydrogen to give 2 moles of ammonia.
Therefore, the mole ratio of NH3 to N2 is 2:1
The Earth, Mars or Jupiter should be denser than the Sun. Density is defined by mass and volume — components of object or matter. Although the sun is huge, it’s component is made up of mostly gas (hydrogen and helium). While Earth, though smaller than the Sun, contains heavier elements such as iron, sulfur, rocks, sediments, granite, basalt and water. Mars (composed of rocks and nutrients) and Jupiter (contains gases and compounds) as well are denser when compared to the Sun’s density. Referencing to our basic understanding of matter: solid and liquid should be heavier than gas.
