Ice floats after it crystallizes because ITS DENSITY IS LESS THAN THAT OF WATER.

When a quantity of water is cools down by reducing its temperature, the molecules of the water lose kinetic energy and slow down in their movement. As the water is cooling down, it is volume is expanding. When the temperature reaches zero degree Celsius, the water becomes ice. At this point, the ice can float on water because its density is less than that of water; this is as a result of the spaces that now exist in the ice structure.

Phantasy [73]

Answer:

  1. Volatile organic compounds
  2. secondary pollutants or photochemical substances
  3. Air Quality
  4. Air pollution
  5. Aerosols

Explanation:

Volatile organic compounds are the  organic chemicals that get easily vaporized in air.

The secondary chemicals or the secondary pollutants are the photochemical substances that are formed in the presence of sunlight.

The amount of gases and small particles present in the atmosphere, responsible for influencing ecosystem and the wellness of human beings is known as the Air Quality

Air pollution refers to the high concentrations of gases or small particles that are present in the atmosphere, which can cause harm to the humans and other living organisms and structures established by humans.

Aerosols are the tiny particles present in liquid or solid state, that are suspended in air.

Convert 0.000371 into scientific notation
Svetach [21]
First look at the numbers. Notice that this is in decimal form. When it's in decimal form, you have to move the decimal to the right until you see a different number other than 0. Therefore, starting with decimal, move it to the right 4 times since a # bigger than 0 is there. 0.000371 - - - - The answer will be 3.71^-4 If it is in decimal form, the power will be a negative
