What is the physical state of helium at room temperature

Chemistry

Depending on the exact room temp, say the helium is in a plastic (one of the ones you buy already full of helium) balloon. Now, you should notice the balloon may be a little squishy, but it is still afloat and looking happy. If you took it outside on a cold day, it would deflate, but when you take it back inside where it is warm, it will reinflate. This is called Boyle's Law. Think if it as if the Helium molecules are partying in the balloon, but when they go out in the cold, they huddle together for warmth.

In a 0.20 M solution, a weak acid is 3.0% dissociated.(a) Calculate the [H₃O⁺] , pH , [OH⁻], and pOH of the solution.
marin [14]

H₃O⁺ = 6.0×10^{-3}

OH = 1.7×10^{-12}

pH = 2.22

pOH = 11.78

<h3>What is pH?</h3>

The term pH, which originally stood for "potential of hydrogen" (or "power of hydrogen"), is used in chemistry to describe how acidic or basic an aqueous solution is. Lower pH values are summarized for acidic solutions (solutions with higher H+ ion concentrations) than for basic or alkaline solutions.

The pH scale is inversely indicates to the concentration of hydrogen ions in the solution and is logarithmic.

⇒pH = -log(a_{H+})

Acidic solutions are those with a pH below 7, and basic solutions are those with a pH above 7, at a temperature of 25 °C (77 °F). At this temperature, solutions with a pH of 7 are neutral (e.g. pure water). The pH neutrality relies on temperature, falling below 7 if the temperature rises above 25 °C.
