If the inital pressure of an ideal gas at a temperature of 344 K is 0.917 atm, what is the pressure of the gas at 322 K?

The teacher is mostly talking about the distillation of a mixture

Answerδh > 0explanationc₆h₆  (s)  → c₆h₆ (l)if you are changing it from a solid to a liquid, you are pretty much melting the solid. this requires heat energy. therefore, the reaction is endothermic (takes in energy); the system enthalpy increases as the reaction proceeds: δh > 0.

For a collision to be successful you need 2 different objects
