use dimensional analysis and the heat vaporization table. Water = 40.7 kj/mol. Start with the information that you were given and make sure that all of your units cancel out! (50.0mL)(1.00g/1mL)(1 mole H2O/18.0g H2O)(40.7kj/1 mole H2O) = 113.0 kj. There are 3 significant ...

Woops! 125km/hr is 34.7m/s so 34.7*14.3 is 496.21m

Givens: a=-9.81m/s^2 d=-1001m vi=0m/s d=vit+1/2at^2 -1001m=1/2-9.81m/s^2t^2 -1001m=-4.905m/s^2t^2 divide -1001m by -4.905m/s^2 204s^2=t^2 square root both sides 14.3s=t 125km/hr is 56m/s 56*14.3= 800.8m, that's the distance from the package dropped.

Ok, i understand that for real gases you have to account for volume of particles, and that they have attractive forces that lower the pressure, that make the ideal gas law invalid, but what does that have to do with low temp and high pressure?

Chemistry
Is it because at high pressure, molecules have volume, and at low temperature gases move slowly and act like a liqud so they have attractive forces that decrease pressure?

Chemistry
I dont know what you just said, but i know that when an ideal gas is at a lower pressure, the molecules do not collide with the container as frequently, and that at a high temperature the molecules do collide frequently. What does this mean, does it even help me?
