What is the color of the stars with the highest temperature

Answers

Answer 1

Answer: The color of a star is a function of its temperature.

For example:

1- If a star looks red that means that its temperature is approximately 2,500 Kelvin.
2- Our Sun, which actually looks white from space, measures about 6,000 Kelvin.
3- The hotter the star, the further up the spectrum you go. The hottest stars are the blue ones. A star appears blue once its surface temperature goes above 10,000 Kelvin or so, a star will appear blue to our eyes.

Just a fact: The hottest star known in the Universe are the blue hypergiant stars. These are stars with more than 100 times mass of the Sun. One of the best known examples is ''Eta Carinae'' that is located about 7,500 light-years from the Sun. ''Eta Carinae'' could be as large as 180 times the radius of the Sun, and its surface is 36,000 - 40,000 Kelvin.

Well hope i helped! I f you need anything more ask me! And think about Eta Carinae is super hot, like wow, 40,000 Kelvin is like 79,000 degrees F. So thats hot, like no joke is super hot.

A 500 gram piece of metal has a volume of 2.75cm3 what is the density

Answers

Answer: $181.82\ g/cm^3$

Explanation:

Given that the volume of a piece of metal = $2.75\ cm^3$

Mass of piece of metal= 500 g

Formula to calculate the density is given by :-

$\text{Density}=\frac{\text{Mass}}{\text{Volume}}$

Then, the density of piece of metal is given by :-

$\text{Density of piece of metal}=(500)/(2.75)\n\n\Rightarrow\ \text{Density}=181.818181818\approx181.82\ g/cm^3$ [Rounded to the nearest two decimal places.]

Hence, its density of piece of metal= $181.82\ g/cm^3$

density is mass / volume so it is 500 / 2.75=181.82 g/cm3

What does energy transformation mean

Answers

Energy transformation or energy conversion is the process of changing one form of energy to another form of energy. In physics, the term energy describes the capacity to produce certain changes within any system, without regard to limitations in transformation imposed.

Consider the following reversible reaction. 2H2O(g)<—>2H2(g)+O2(g) What is the equilibrium constant expression for the given system?

Answers

Answer : The equilibrium constant expression will be,

$k_(eq)=([H_2]^2[O_2])/([H_2O]^2)$

Explanation :

The given balanced chemical reaction is,

$2H_2O(g)\rightleftharpoons 2H_2(g)+O_2(g)$

The equilibrium expression for the reaction is determined by multiplying the concentrations of products and divided by the concentrations of the reactants and each concentration is raised to the power that is equal to the coefficient in the balanced reaction.

The concentrations of pure solids are constant that is they do not change. Thus, they are not included in the equilibrium expression.

So, the equilibrium constant expression will be,

$k_(eq)=([H_2]^2[O_2])/([H_2O]^2)$

Answer: D
