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.

Why can’t cold air hold much water vapor?
Andru [333]
Warm air can “hold” more water vapor than cool air because as the air warms its molecules move farther apart, making room for more molecules. This leads to the idea that as air cools its molecules move closer together, “squeezing” out water vapor.

Calculate the percentage of water of crystallisation in MgSO⁴ 7H²O
Bas_tet [7]

Answer:

Formula of EPSOM salt = MgSO4.7H2O

molecular mass of MgSO4.7H2O = atomic mass of Mg + atomic mass of S + 4 × atomic mass of O + 7 { 2 × atomic mass of H + atomic mass of O }

= 24 + 32 + 4× 16 + 7{ 2 × 1 + 16 } g/mol

= (24 + 32 + 64+ 126 ) g/mol

= 246 g/mol

molecular mass of total water = 7 × ( 2× atomic mass of H + atomic mass of O )

= 7 × 18 = 126 g/mol

now ,

% mass of H2O in EPSOM salt = {total molar mass of H2O/molar mass of Epsom salts }× 100

= {126/246 } × 100

= 12600/246

= 51.21 %
