For a van der waals gas, t = a/vm? . calculate aun for the isothermal expansion of nitrogen gas from an initial volume of 1.00 dm to 28.35 dmº at 298 k. (the default units for um are kj mol! )

When the speed of the bottle is 2 m/s, the average maximum height of the beanbag is m.

What amount of heat is exchanged when 106.2 grams of substance y goes from a liquid at 35 degrees celsius to a solid at the same temperature? melting point of substance y = 35 degrees c; δhvaporization = 3.67 j/mol; δhfusion = 3.30 j/mol. mwsubstance y = 28.22 g/mol. −12.4 j −3.51 x 102 j 1.24 x 101 j 351 j

The term gas is limited to those substances that exist in the gaseous state at
