Distillation is a technique used to separate pure liquids from a mixture of liquids by boiling the mixture to the respective boiling points of the components and selective condensation. The pure liquid separated out after the condensation of vapors is called distillate. The distillate collected is expected to be pure. The purity of the distillate can be measured by recording the boiling point of that liquid. For example, if we have water separated out it should boil at 100 otherwise it can be treated as impure.
A) Answer D. Clouds forming high in the atmosphere are referred to as cirrus, cirrostratus, and cirrocumulus.
B) Clouds tend to form at higher altitudes because as<span> air rises, the moisture in it slowly reaches its saturation point and when this happens, tiny crystals of water start to condense and form clouds.
C) Precipitation: Water that falls to the ground from clouds, such as in rain, snow, sleet, or hail.</span>
All of the choices would affect the rate
Answer:
353kg
Explanation:
2000 x 0.1765 = 353kg
for every 1 cubic metre of helium there is 0.1765 kg of it
the balloon is holding 2,000 cubic metres of the helium.
That means that there are 2000 times of 0.1765kg of helium in the balloon
so you times 0.1765kg by 2000
Answer:
Democritus
Explanation:
Democritus was a Greek philosopher that first conceptualize the idea of an atom. He suggested matter to be composed of atoms, which move through empty spaces. Democritus explained that different kinds of atoms have different sizes and shapes.
His proposition was not made into a theory by the scientific community of that time because there was barely little to no evidence to support the findings. The technology as a that time were not sophisticated to back up these claims.
