Condensation nuclei, tiny particles of matter in the air, are important because ________.
kolbaska11 [484]

Condensation nuclei which are tiny particles of matter in the air are important as they provide a surface for water vapors to form water molecules on it.

<h3>What is Condensation Nuclei?</h3>

It is defined as the tiny particles in the surrounding atmosphere where water vapor condenses to form a water droplet or ice particle.

The water vapor in the atmosphere needs something to stick to for condensation to occur

Condensation nuclei are the particles floating in the atmosphere which include dust, dirt, forest fire ash, factory smoke and pollution, volcanic ash, salt from ocean spray, and sulfate particles that are emitted by phytoplankton.

On land, Grass, twigs, and windshields act as the surface for water vapor on which they condense to form dew and frost.

Likewise, the Condensation Nuclei act as a surface in the atmosphere.

Thus, Condensation Nuclei are important as they provide a surface for the water vapors to condense and form water molecules like water droplets and ice particles.

6) A rectangular fish tank is 70.00 cm long, 300.00 mm wide, and 300.00 m deep.
KATRIN_1 [288]

Answer:

Volume of water it can hold 63000,000 cm³

Mass of water is 63000,000 g.

Explanation:

Given data:

Length of tank  = 70.00 cm

Width of tank = 300.00 mm

Height of tank = 300.00 m

Volume of water it can hold  = ?

Mass of water = ?

Solution:

First of all we will convert the units into same unit.

Width of tank = 300.00 mm × 1 cm / 10 mm = 30 cm

Height of tank = 300.00 m× 100 cm / 1 m = 30000 cm

Volume of water it can hold:

V = l×w×h

V = 70.00 cm × 30 cm × 30000 cm

V = 63000,000 cm³

Mass of water:

Density of water from literature = 1 g/cm³

d = m/v

1 g/cm³ = m/ 63000,000 cm³

m = 63000,000 g
