Answer: physical
Explanation: freezing and melting are physical changes.
Ductility because ductility is the ability to be stretched and be made into wires.
Answer:
The concentration of the copper sulfate solution is 83 mM.
Explanation:
The absorbance of a copper sulfate solution can be calculated using Beer-Lambert Law:
A = ε . c . <em>l</em>
where
ε is the extinction coefficient of copper sulfate (ε = 12 M⁻¹.cm⁻¹)
c is its molar concentration (what we are looking for)
l is the pathlength (0.50 cm)
We can use this expression to find the molarity of this solution:

Given the speed, you will travel 195km in 3 hours.
65 x 3 = 195
