Answer:
P₂ = 1.0 atm
Explanation:
Boyles Law problem => P ∝ 1/V at constant temperature (T).
Empirical equation
P ∝ 1/V => P = k(1/V) => k = P·V => for comparing two different case conditions, k₁ = k₂ => P₁V₁ = P₂V₂
Given
P₁ = 1.6 atm
V₁ = 312 ml
P₂ = ?
V₂ = 500 ml
P₁V₁ = P₂V₂ => P₂ = P₁V₁/V₂ =1.6 atm x 312 ml / 500ml = 1.0 atm
Answer:
No, of itself a pencil sharpener is not kinetic or potential energy. However, due to its position in a gravity field, a pencil sharpener on a desk does have potential energy.
Explanation:
Answer:
A). CH4.
Explanation:
Ar and Mg are elements.
LiBr and NaI are ionic compounds.
CH4 has 4 covalent bonds between the carbon and hydrogen atoms.
Antimony cannot be broken down by chemical means because it is an element, a principle building block of matter. All other choices are compounds, which can be separated if put through enough stress to break the bonds between the atoms.
Material C. the less dense is easier to move through than the more dense, so the light moves faster. Its like light moving through less dense glass, then moving through a more dense wall.
