Final answer:
The little black sand-shaped particles are likely bits of broken glass or debris in the window frame with holes.
Explanation:
The little black sand-shaped particles in a window frame with holes are most likely bits of broken glass or debris.
When glass is broken, it can shatter into tiny fragments that resemble black sand. These particles can accumulate in the corners or along the edges of a window frame.
To prevent this, it is important to replace any broken glass and clean the window frame regularly. This will maintain the integrity of the window and ensure a clear view.

Final Answer:
The little black sand-shaped particles in a window frame with holes are likely to be desiccants, commonly silica gel beads.
Explanation:
The presence of small black sand-shaped particles in a window frame often indicates the use of desiccants, with silica gel beads being a common choice. Desiccants are materials that have the ability to absorb and hold moisture from the surrounding environment. Silica gel is a popular desiccant due to its high absorbent capacity and stability.
Window manufacturers often incorporate desiccants within the window frames to help control humidity levels and prevent condensation or fogging of the glass. When windows have small holes or gaps, moisture can infiltrate the frame, potentially leading to issues like mold growth, reduced insulation efficiency, or damage to the window components.
Silica gel beads are tiny, granular particles that appear as black sand-like grains. They are engineered to adsorb moisture efficiently, reducing the humidity inside the window frame. By doing so, they help maintain a dry environment, preventing problems associated with excess moisture, such as corrosion and deterioration of the window's structural integrity.
