What is ductile and malleability?
You can do what I just did.
Google ductile definition and malleability definition.
Malleability-easily broken
Ductile-easily wired
No.

WOW
Can we ALL agree that's the biggest link ever!
YASS!
Heat, in scientific terms, can be defined as the energy transfer between objects or systems due to a difference in temperature. It is a form of energy that flows from a higher temperature region to a lower temperature region, until both regions reach thermal equilibrium (the temperatures equalize). Heat is measured in units such as joules (J) or calories (cal).
To understand heat further, it is important to understand the concept of temperature. Temperature is a measure of the average kinetic energy of the particles in a substance. When objects or substances with different temperatures come into contact, the particles with higher kinetic energy (higher temperature) transfer some of their energy to the particles with lower kinetic energy (lower temperature). This energy transfer is what we refer to as heat.
Heat transfer occurs through three main mechanisms: conduction, convection, and radiation.
1. Conduction: This mechanism involves the transfer of heat through direct contact between objects or substances. In solids, heat is conducted through vibrations and collisions between particles. Good conductors, like metals, allow heat to transfer more easily, while insulators, like wood or plastic, impede heat transfer.
2. Convection: Convection involves the transfer of heat through the movement of a fluid, such as air or water. When a fluid is heated, it becomes less dense and rises, creating a flow of hot fluid upward. Conversely, cooler fluid sinks, creating a circulation that transfers heat from one region to another.
3. Radiation: Radiation is the transfer of heat through electromagnetic waves, such as infrared radiation. Unlike conduction and convection, radiation does not require a medium to propagate and can transfer heat through empty space. An example of this is the heat we receive from the Sun.
In summary, heat is the transfer of energy between objects or systems due to a temperature difference. Understanding the mechanisms of conduction, convection, and radiation can help explain how heat is transferred in various scenarios.
