Help! Need it ASAP!<br> Is steam and vapour different? If they are then how are they different?
Alexxx [7]

Answer:

Explanation:

Water vapor is when water molecules are present in the air, while steam is water heated to the point that it turns into gas. In simplified science, both are referred to as the gaseous state of water. Steam is usually white or translucent in nature, while water vapor can be clear or translucent.

Steam is simply, water vapor. Hence, the key difference between steam and vapor is that steam is the gaseous state of water whereas vapor is the gaseous state of any substance. Moreover, steam is typically invisible while the vapor of some substances is colorful.

the density of gold is 19.3 g/cm3. a 3.4 mg piece of gold is hammered into a square that is 8.6 x 10-6 cm thick. what is the len
faltersainse [42]

Answer:

The length of a side of the square is 4.53 cm

Explanation:

Volume (V) = mass/density

mass = 3.4 mg = 3.4/1000 = 0.0034 g

density = 19.3 g/cm^3

V = 0.0034/19.3 = 1.76×10^-4 cm^3

Volume = area × thickness

Area = volume/thickness = 1.76×10^-4/8.6×10^-6 = 20.48 cm^2

Length of one side of the square = sqrt(area of square) = sqrt(20.48 cm^2) = 4.53 cm
