Answer:
Explanation:
Brittleness : The ability of an object to break apart or shatter easily
Ductility: The ability of a substance to be stretched out into a long wire-like shape.
Lustre: the ability of an object to reflect light.
Malleability is a substance's ability to deform under pressure
The melting point of ice is 0°C. The melting point of a solid is the same as the freezing point of the liquid
Solubility is the relative ability of a solute to dissolve into a solvent.
solid: Has a definite shape and volume.
liquid: Has a definite volume, but take the shape of the container.
gas: Has no definite shape or volume. change of state
The resistance of a liquid to flowing is its viscosity.

Answer:
133.3atm
Explanation:
Given parameters:
Initial volume = 400ft³
Final volume = 3ft³
Initial pressure = 1atm
Unknown:
Final pressure = ?
Solution:
To solve this problem, we apply Boyle's law which states that "the volume of a fixed mass of a gas varies inversely as the pressure changes if the temperature is constant".
Mathematically;
P₁V₁ = P₂V₂
P and V are pressure and volume
1 and 2 are initial and final states;
Insert parameters and solve;
1 x 400 = P₂ x 3
P₂ = 133.3atm
Atomic Mass Number = Atomic Number + Number of Neutrons
Answer: Two of the strongest forms of chemical bond are the ionic and the covalent bonds. Chemical bonds form between two atoms, each with its own electron environment. If each of the two atoms shares an electron with the other atom nearly equally, the bond is called covalent.
