If there are 4 different gases in a room and the room seems to have a high pressure within it because you keep getting headaches, what would you do to find the total amount of pressure in the room?

What do you mean by that? like the contents? the thc level?

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.
