C Correct answer
Explanation

Surface energy is the energy required to create a new surface, and it is directly proportional to the work done in the process.

Multiple choice

What is a phase transformation?

  1. A change in the crystal structure of a solid material

  2. A change in the composition of a solid material

  3. A change in the physical properties of a solid material

  4. A change in the chemical properties of a solid material
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A phase transformation is a change in the crystal structure of a solid material, resulting in a new phase with different properties.

Multiple choice

What is a nucleation and growth process?

  1. A process by which a new phase forms from a homogeneous solution

  2. A process by which a new phase forms from a heterogeneous solution

  3. A process by which a new phase forms from a solid phase

  4. A process by which a new phase forms from a liquid phase
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

A nucleation and growth process is a process by which a new phase forms from a homogeneous solution, involving the formation of small clusters of atoms or molecules (nuclei) that grow by attaching additional atoms or molecules from the solution.
