Radiation _____.

Chemistry
1 answer:
AURORKA [14]3 years ago
6 0

Answer:

Option (d) is the correct answer.

Explanation:

Radiation is defined as electromagnetic energy that travels in space in the form of waves or particles.  This means that heat energy will always travel from a warmer object to a colder object.  For example, radiations coming from the Sun are able to transfer heat energy to the substance on which they fall.  Thus, we can conclude that radiation is the method of heat transfer used by the Sun.

¿como afecta la<br> temperatura el <br> volumen de un gas?
Oxana [17]

Lo afect porque cuando la temperature aumenta, el volumen aumentará, luego, cuando we mantiene la presión, es constante. Calentar el gas aumenta la emergía cinética we law partículas, lo que have que el gas se expanda.

Espero que esto ayude :)

Filtration and dialysis are techniques that rely on differences in particle size to separate mixture components. True False
soldier1979 [14.2K]

This is true. Think about when you make pasta. The colander acts as a filter and doesn't let the past a through but allows the extra water to escape because the pasta is too big to fit.

Which compound decreases in solubility as the temperature of the solution is increased from 10c to 50c
Marysya12 [62]

Answer:

<u><em></em></u>

  • <u><em>2)NH</em></u><em><u>₃</u></em>

Explanation:

The answer choices of this question are:

  • 1)NH₄Cl
  • 2)NH₃
  • 3)NaNO₃
  • 4)NaCl
<h2 /><h2>Solution</h2>

The key to answer this question is to realize that <em>NH₃</em> is a gas at the given temperatures.

The solutilibty of all gases always decreases when the temperature increases. Thus, the solubility of NH₃ will decrease when the temperature rises from 10ºC to 50ºC.

The reason for this behavior of gases is that the temperature and the kinetic energy of the particles are directly proportional. Thus, as the temperature incrases the kinetic energy of the particles increases.

As the kinetic energy of the molecules of gas in the liquid solution increases, their speeds also increase, meaning that more molecules will escape from the solution to the gas phase, leaving the soluton with less dissolved gas molecules.
