Some animals hunt by <em>Camouflage</em> or sneaking up on their prey.
The boiling point of a substance is a physical property.
A physical property of a material or substance is one that can be observed without changing or altering the composition of the material.
Examples are mass, Density, Color, solubility, boiling point, melting point .
A chemical property of a substance is one that describes how the material changes into a completely different substance and is observed only during a chemical reaction.
Examples of chemical properties include types of chemical bonds, heat of combustion, reactivity with other metals, oxidation state and enthalpy of formation.
Answer:
Explanation:
The density formula is:
Rearrange this formula for v, volume. Multiply by v, then divide by d.
Volume can be found by dividing the mass by the density. The mass of the aluminum is 45.6 grams and the density is 2.1 grams per milliliter.
Divide. Note the grams, or g, will cancel out.
The volume of the aluminum is 21.7142857 milliliters.
