Brief Explanations:
A physical change is a change in the form or appearance of a substance without changing its chemical composition. For example, melting ice is a physical change as water changes from solid to liquid but is still H₂O. A chemical change results in the formation of a new substance with different chemical properties. Burning wood is a chemical change as wood reacts with oxygen to form carbon dioxide, water vapor, and ash.
Answer:
Physical change: change in form without chemical composition change, e.g., melting ice. Chemical change: formation of new substance, e.g., burning wood.

Explanation:
Step1: Identify the operation
We need to find half of $\frac{2}{3}$, which means multiplying $\frac{2}{3}$ by $\frac{1}{2}$. $\frac{2}{3}\times\frac{1}{2}$
Step2: Multiply the numerators and denominators
Multiply the numerators $2\times1 = 2$ and the denominators $3\times2=6$. So, $\frac{2\times1}{3\times2}=\frac{2}{6}$.
Step3: Simplify the fraction
$\frac{2}{6}$ can be simplified by dividing both the numerator and denominator by 2. $\frac{2\div2}{6\div2}=\frac{1}{3}$.
Answer:
$\frac{1}{3}$ cup of flour.
