What effect will decreasing the temperature of a liquid by 15 °C at constant pressure have on the magnitude of its vapor pressure?

Predict the predominate intermolecular force (London force, dipole-dipole, or hydrogen bonding) that would be associated with each of the following compounds. -HCl ______________________________

Which statement about the boiling point of water is incorrect?

) In the calculation set-up below to determine how much heat is needed to convert 50 g of ice at ?20 °C to steam at 300 °C, which constant does C represent? (A)(50 g)(20 °C) + (heat of fusion)(50 g) + (B)(50 g)(100 °C) + (heat of vap.)(50 g) + (C)(50 g)(200 °C) = total heat
