What is the hottest planet?

VenusVenus is the exception, as its proximity to the Sun and dense atmosphere make it our solar system’s hottest planet. The average temperatures of planets in our solar system are: Mercury – 800°F (430°C) during the day, -290°F (-180°C) at night.

What causes flame color?

The colors of a flame are caused by bits of wax molecules that didn’t get completely reacted. These glow a certain color when they get to be a certain temperature. Since different parts of the flame have different temperatures, these bits of wax molecules make those areas of the flame glow with different colors.

What gas is green in color?

Chlorine is a halogen gas that has a common salt and has very light green color.

Does fire have a shadow?

What is the coldest flame color?

The colder part of a diffusion (incomplete combustion) flame will be red, transitioning to orange, yellow, and white as the temperature increases as evidenced by changes in the black-body radiation spectrum. For a given flame’s region, the closer to white on this scale, the hotter that section of the flame is.

Is a shadow two dimensional?

A shadow is a dark (real image) area where light from a light source is blocked by an opaque object. It occupies all of the three-dimensional volume behind an object with light in front of it.
