Crystalline solids do not have a sharp melting point.

TRUE

FALSE

Answers

Answer:

False

Explanation:

A crystalline solid has a well ordered structure. The particles that make up the solid are arranged in a regular repeating pattern. When the solid is heated, this structure gives way, in order words, the solid melts.

Pure solids crystals are known to have sharp melting points. This is a property of crystalline solids.

The statement about “Crystalline solids do not have a sharp melting point” is false. Crystalline solids are solids that have particles arranged in a regular, repeating patterns. They are held together by uniform intermolecular forces. The faces intersect at a specific angle that identifies that substance. They have distinctive internal structures that in turn lead to distinctive flat surfaces. These flat surfaces give a short rage order. When exposed to x – ray diffractometers, they exhibit a distinctive pattern used to identify the material. They give the same face when you turn a crystalline solid around

 

What are some uses of metals?

A balloon is a sphere with a radius of 5.0 m. The force of air against the walls of the balloon is 45 N. What is the air pressure inside the balloon? (surface area = 12.56 x radius^2; 1 Pa = 1 N/m^2)A. 1.4 x 10^3 Pa

B. 3.6 x 10^2 Pa

C. 1.4 x 10^-1 Pa

D. 3.6 x 10^-2 Pa

***Idk how to solve this... pls explain?? thx :)

Answers

Pressure is the force exerted on an object per unit area. The equation is expressed as:

P = F / A

From the given above, we substitute the values to the equation.

P = F/A
P= F / (12.56r²)
P = 45 N / (12.56 x 5²
P = 0.143 N/m²

Therefore, the correct answer is option C, 1.4 x 10^-1 Pa.

Abdid is an astronomer who has been observing objects that orbit the Sun in the asteroid belt. He finds a previously undiscovered round, rocky object that is not similar in shape to the rest of the asteroids. What has Abdid most likely found?

Answers

Answer:

Abdid has most likely found a new dwarf planet.

Explanation:

Dwarf planets are too small to be considered planets, but are also two big to be considered something else. A dwarf planet has to have sufficient mass so that the self-gravity is strong enough to create its round shape. Other qualifications of a dwarf planet is that it has not cleared the neighborhood around its orbit and it cannot be a satellite. Based on the location, size, and shape of the object Abdid has discovered, it is likely he discovered a new dwarf planet in the asterioid belt. One of the most famous is Ceres.

since it is round and it is the asteroid belt it is most likely that he found a dwarf planet
