The answer is C) 373 Kelvin, 100 degrees Celsius, 212 degrees Fahrenheit. This is the boiling point of water.

Hope this helps! :)

Ans: C

Temperature can be expressed in terms of :

Kelvin (K), Celsius (C) or Fahrenheit (F)

The three units are interchangeable.

1) Kelvin(K) and Celsius(C)

K = 273 + C ----(1)

2) Celsius(C) and Fahrenheit(F)

F = (C*9/5) + 32 ---(2)

Option C is correct because:

From eq(1), when C = 100

K = 273 + 100 = 373

From eq(2), when C = 100

F = (100*9/5)+32 = 212

Y’all what’s this I don’t feel like doing it and I’ll give brainlist too

Answer:

2.Closed System: A closed system is a thermodynamic system where energy can be exchanged with its surrounding but not matter. Open System: Open systems can exchange matter with the surrounding. Closed System: Closed systems cannot exchange matter with the surrounding. Open System: The mass of the system will vary with time in open systems.

Explanation:

1.The particle model is the name for the diagrams used to draw solids, liquids and gases. In the model, the particles are shown as circles or spheres. However, the particles in ice, liquid water and steam look the same because they are all water, but in different states of matter. Why do we use the particle model in science?

3.An open system can be defined as a system which can exchange both matter and energy with the surrounding. For example, the earth can be recognized as an open system. In this case, the earth is the system, and space is the surrounding. Sunlight can reach the earth surface and we can send rockets to space.

Calculate the speed of light in an unknown substance whose index of refraction is 1.65. Would you expect the light to bend towar
Anna71 [15]

(a) The speed of light in the unknown substance is determined 1.82 x 10⁸ m/s.

(b) The light will bend away from the normal since speed of light in air is not equal to speed of light in the substance.

<h3>What is the speed of light?</h3>

The speed of light passing from air into the substance is calculated as follows;

refractive index = speed of light in air / speed of light in the substance

speed of light in the substance = speed of light in air/refractive index

speed of light in the substance = (3 x 10⁸) / (1.65)

speed of light in the substance = 1.82 x 10⁸ m/s

Thus, the light will bend away from the normal since speed of light in air is not equal to speed of light in the substance.

The electronegativity is 2.1 for h and 1.9 for pb. based on these electronegativities pbh4 would be expected to
Sedbober [7]
PbH4 will be formed as a result of a polar covalent bond between the H and the Pb.

Since H is more electronegative than the Pb, it is, thus, expected that the H would be able to pull the electron charge towards itself. This will result in the H being negative.

Based on this:
PbH4 would be expected to <span>have polar covalent bonds with a partial negative charges on the H atoms. </span>
