Thermochromic Materials and Heat Energy for Grade 5

These flashcards cover vocabulary and key concepts from the lecture on thermochromic materials and how heat affects them for a Grade 5 understanding.

Thermochromic

Materials that change color when their temperature changes.

Thermal Energy

Energy from heat, which affects the motion of molecules.

Reversible Change

A change that can be reversed, allowing the original state to return.

Molecules

The smallest units of a substance, composed of atoms, that retain the properties of that substance.

Color Change

The alteration of color, which happens in thermochromic materials due to changes in energy.

Energy Transfer

The process of energy moving from one system or object to another.

How Heat Affects Molecules

Heat causes molecules to move faster, which can result in a change of shape and color.

Frixion Pens

Pens that use thermochromic ink allowing for reversible writing when heat is applied.

Misconception Correction

Addressing misunderstandings about concepts, such as confusing thermal energy with chemical energy.
