Answer:
The particle model represents particles by small, solid spheres.It describes the arrangement, movement and energy of particles in a substance. The model can be used to explain the physical properties of solids, liquids and gases.

Answer:
All of the following statements are true regarding wood versus metal except:
c) Under sustained loads wood stops to deform
Explanation:
Wood is known to deform under stress. It undergoes warping, thereby, losing its original straight shape when its moisture unevenly dries up. Even concrete deforms under long-time loads. Similarly, wood, under sustained loads, experiences faster deformation than it ordinarily warps. To prevent further wood deformation, it must be treated, and its moisture dried up evenly.
What is the question? Explain what answer you need(
Answer:
See explanation
Explanation:
Sublimation refers to the movement of molecules directly from solid into the vapor or gas phase while deposition refers to the movement of molecules directly from the gas phase into the solid phase. The two are opposite to each other.
Frost is formed in a situation where a substance cools to a temperature that is lower than its dew point. In this situation, the vapour is directly deposited on a surface to form a frost without passing through a liquid phase. Hence the name, deposition.
