Radon-222 transforms into polonium-218 and an alpha particle (he-4). what else is created?

1 answer:

6 0

Hm pretty much that's all for alpha decay... But always after any alpha or beta decay, gamma photons are released because the daughter products end up in an excited state so they have to release energy through gamma decay

It is dangerous to stand near the railway leak when train passing by,why?

4vir4ik [10]

Answer:

Because a person may be pulled in the direction of the moving train. Thereby causing accident

Explanation:

According to Daniel Bernoulli's theorem, he was widely known as a Mathematician. He stated that due to the higher velocity of a moving train, there is higher kinetic energy in terms of volume around it, while the air pressure between the person and the train becomes lower.

As a result, a person near a moving train may be pulled in the direction of the moving train. Thereby causing accidents that may lead to death.

When the temperature of an ideal gas is increased, the pressure also ________

kherson [118]

<h2>Answer: increases </h2><h2 />

Explanation:

The expression for an Ideal Gas is:

$P.V=n.R.T$

Where:

$P$ is the pressure of the gas

$V$ is the volume of the gas

$n$ the number of moles of gas

$R$ is the gas constant

$T$ is the absolute temperature of the gas

As we can see, there is a <u>direct proportional relation between the temperature and the pressure</u>, which means that if the temperature increases the pressure of the gas increases as well.

However, it is important to note this is fulfilled if and only<u> if the volume of the container where the ideal gas is, remains constant.</u>

In order to answer this, we would need to know
the half-life of ⁴⁰K. Perhaps when you look that up,
you'll be able to answer this on your own.
