Based on exposure time and place, the Sun's radiation may have harmful or beneficial effects.

<h3>What is solar radiation?</h3>

Solar radiation refers to the radiation from the Sun in the form heat, light and other forms of radiation.

The radiation from the Sun may have harmful or beneficial effects.

The effects of the Sun's radiation can be classified as BE, HE or SP as follows:

  • BE- UV rays can help treat some health conditions. It creates Vitamin D
  • SP- Use sunblock lotion with SPF 15 during hot days.
  • BE- With the presence of sunlight, farmers can dry their crops.
  • HE- UV rays can damage the tissue in your eyes.
  • BE- Research says that sunlight helps moods.
  • HE- Too much exposure from the sun can cause skin cancer.
  • SP- Use sunglasses when you stay under the sun.
  • SP- Wear a wide- brimmed hat on sunny days.
  • BE- Humans can do recreational activities on a sunny day.
  • SP- Wear sunglasses that filter UV light.
  • HE- Prolonged exposure to the sun’s heat makes your skin age faster than normal.
  • HE- Too much heat from the sun can cause heat stroke and loss of water.
  • BE- Sunlight helps strengthen your immune system.
  • BE- The vitamin D made thanks to the sun plays a big role in bone health.
  • SP- Avoid sun in the middle of the day, from about 10 a.m. to 3 p.m.

A container of gas has a volume of 280 mL at a temperature of 22 Celsius if the pressure remains constant what is the volume 44
d1i1m1o1n [39]

Answer:

300.9mL

Explanation:

Given parameters:

V₁  = 280mL

T₁ = 22°C

T₂  = 44°C

Unknown:

V₂ = ?

Solution:

To solve this problem, we apply Charles's law;

  it is mathematically expressed as;

            \frac{V_{1} }{T_{1} }  = \frac{V_{2} }{T_{2} }

We need to convert the temperature to kelvin;

       T₁ = 22°C = 22 + 273 = 295K

       T₂  = 44°C = 44 + 273  = 317K

Input the parameters and solve;

        \frac{280}{295}   = \frac{V_{2} }{317}

  V₂ x 295 = 280 x 317

  V₂ = 300.9mL

What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron?
vazorg [7]

Answer:

<em>What can be added to an atom to cause a nonvalence electron in the atom to temporarily become a valence electron </em>is<u><em> energy</em></u><em>.</em>

Explanation:

The normal state of the atoms, where all the electrons are occupying the lowest possible energy level, is called ground state.

The <em>valence electrons</em> are the electrons that occupy the outermost shell, this is the electrons in the highest main energy level (principal quantum number) of the atom.

So, a <em>nonvalence electron</em> occupies an orbital with less energy than what a valence electron does; in consequence, in order to a nonvalence electron jump from its lower energy level to the higher energy level of a valence electron, the former has to absorb (gain) energy.

This new state is called excited state and is temporary: the electron promoted to the higher energy level will emit the excess energy, in the form of light (photons), to come back to the lower energy level and so the atom return to the ground state.

Try to make only one molecule of water in the simulation. Is it possible?
mel-nik [20]

Answer:

A single molecule of water has been isolated for the first time by trapping it in a fullerene cage. Water molecules are never found alone — they are always hydrogen-bonded to other molecules of water or polar compounds.

While making small volumes of pure water in a lab is possible, it's not practical to “make” large volumes of water by mixing hydrogen and oxygen together. The reaction is expensive, releases lots of energy, and can cause really massive explosions.

A water molecule consists of three atoms; an oxygen atom and two hydrogen atoms, which are bond together like little magnets. The atoms consist of matter that has a nucleus in the centre. The difference between atoms is expressed by atomic numbers.
