You have a 25.0 L cylinder of helium at a pressure of 132 atm and a temperature of 19 [infinity]C. The He is used to fill balloons to a volume of 2.50 L at 732 mm Hg and 27 [infinity]C. How many balloons can be filled with He? Assume that the cylinder can provide He until its internal pressure reaches 1.00 atm (i. e., there are 131 atmospheres of usable He in the cylinder).

Which statements are true concerning mineral formation? check all that apply. the slower the cooling, the larger the crystals. the faster the cooling, the smaller the crystals. crystals formed from magma are smaller than crystals formed from lava. minerals can only form in solutions when the solution is heated deep underground. when a solution cools, elements and compounds leave the solution and crystallize as minerals. minerals formed from hot water solutions can form narrow channels in the surrounding rock.
