When two objects come in contact with each other, transfer of material takes place in accordance with:
## Core Concept
The phenomenon described refers to the transfer of material between two objects in contact, which is a fundamental concept in physics and materials science. This process is related to the **triboelectric effect** or **contact electrification**, where two objects exchange electrons upon contact, resulting in one object becoming positively charged and the other negatively charged.
## Why the Correct Answer is Right
The correct answer, , relates to the triboelectric series. The **triboelectric series** is a list of materials that gain a positive charge when they come into contact with another material that is higher in the series. This series explains the phenomenon of **contact electrification**, where the transfer of electrons occurs between two objects in physical contact, leading to one becoming positively charged and the other negatively charged. The farther apart two materials are in the triboelectric series, the greater the charge transfer and the stronger the electrostatic attraction between them.
## Why Each Wrong Option is Incorrect
- **Option A:** This option does not directly relate to a recognized principle of material transfer or electrification upon contact. Without a specific principle or phenomenon associated with it, it's hard to assess its relevance.
- **Option B:** Similarly, this option lacks a clear connection to known scientific principles governing material or charge transfer between objects in contact.
- **Option D:** This option also does not correspond to a widely recognized principle or phenomenon related to the transfer of material or charge between objects upon contact.
## Clinical Pearl / High-Yield Fact
A memorable point for exams is that the **triboelectric effect** is the reason why rubbing a balloon on hair makes it stick to walls; the balloon becomes charged and attracts the neutrally charged wall. This principle has implications in various fields, including physics, materials science, and even medicine, where static electricity can affect the behavior of particles in certain medical devices.
## Correct Answer Line
**Correct Answer: C. **
