You need to add 2 to make it correct
Answer:
i think it's true because An element is a substance that is made entirely from one type of atom
Answer:
The laws of the universe are for all observers, and it was shown that the velocity of light in spacetime will be the same regardless of the subject's speed.
Explanation:
The principle outlines how things behave in time and space, so it could be used to model anything from black hole life to light shifting due to the gravitational, as well as the action of the terrestrial Planets in its orbit. Einstein's most popular hypothesis has far-reaching ramifications.
Where, P is the pressure of the gas, V is volume of the gas and T is the temperature of the gas in Kelvin.
For two situations, we can use that as,P₁V₁/T₁= P₂V₂/T₂
P₁ = 795 mm HgV₁ = 642 mLT₁ = (273 + 23.5) K = 296.5 KP₂ = ? V₂ = 957 mLT₂ = (273 + 31.7) K = 304.7 K
By applying the formula,
795 mm Hg x 642 mL / 296.5 K = P₂ x 957 mL / 304.7 K P₂ = 548.07 mm Hg P₂ = 548 mm Hg760 mmHg = 1 atm548 mm Hg = 1 atm x (548 mmHg / 760 mmHg) = 0.721 atm
Pressure of gas = 548 mm Hg = 0.721 atm
