How would a sandblasted rock differ from a rock that hasn't been sandblasted?

Answers

Answer 1
Answer: A non-sandblasted rock could be rough or smooth depending on how it was formed.

A sandblasted rock should be much smoother, since the sand blasts away any rough edges. It will, however, be slightly smaller due to losing those edges.
Answer 2
Answer:

A sandblasted rock differs from a non-sandblasted rock in various aspects, including a change in texture and color of the rock's surface.

Sandblasting is a process in which a high-pressure stream of sand or other abrasive material is used to remove material from the surface of an object.

The most noticeable difference between a sandblasted rock and one that hasn't been sandblasted is the texture of the surface. A sandblasted rock will typically have a rough, pitted surface, while an unsandblasted rock will have a smoother surface.

Sandblasting can also change the color of a rock. If the rock has a layer of surface material that is a different color than the underlying rock, sandblasting can remove the surface layer and expose the underlying rock.

Therefore, a sandblasted rock would differ from a rock that hasn't been sandblasted in several ways such as change in texture and color of a rock's surface, creating a rough, pitted texture and exposing the underlying rock.

What determines the type of element that an atom makes?

Answers

Only the number of protons determine the type of atom. Elements can have more or less neutrons and electrons and still be the same general type of element.
The number of protons, neutrons and electrons an atom has determines what element it is. Hydrogen, for example, has one proton, no neutrons and one electron; the element sulfur has 16 protons, 16 neutrons and 16 electrons.

Please help!!!! A group of students is studying convection currents. They fill two identical balloons with the same amount of helium. One balloon is placed in a freezer and the other in an area with warm air. After 10 minutes, the balloons are released from a height of 1 meter. Which of the following do the students most likely observe? A. The balloons both rise. The cold balloon is larger than the warm balloon.


B. The balloons rise at the same rate. Both balloons are the same size.


C. The warm balloon expands and rises. The cold balloon shrinks and sinks.


D. The cold balloon expands and rises. The warm balloon shrinks and sinks.

Answers

The correct answer is option C, that is, the warm balloon expands and rises, and the cold balloon shrinks and sinks.

It is known from the ideal gas equation, that PV = nRT

Here, P is pressure, V is volume, n is the number of atoms in gas, R is gas constant, and T is temperature.

From the equation, it is clear that the volume of balloon is directly proportional to the temperature. It signifies that at constant pressure when temperature elevates than at that time volume of the balloon will increase and when temperature reduces the volume of balloon will decrease.

Thus, the volume of warm balloon will increase because of which its density increases and it can rises easily as a less dense substance can easily rises in air in comparison to more dense gas or substance. Thus, the cold balloon shrinks and sinks.
