How is the AHfusion used to calculate the energy required to vaporize a volume of liquid?
A. Liters liquid * 1000ml/1L g/ml x mol/g < AHfusion
B. Liters liquid * 1000ml/1L * ml/g *g/mol 1/AHfusion
C. Liters liquid * 1000ml/1L * ml/g * g/mol * A Hfusion
D. Liters liquid x 1000ml/1L x g/ml x mol/g < 1/4Htusion

Freezing and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Voltaic cells produce a positive overall charge. what does this indicate? a. the reaction is likely to be endothermic. b. the reaction is spontaneous. c. the reaction is not likely to occur. d. the reaction is not spontaneous.

Which is true of a liquid? it has a definite volume but not a definite mass.it has a definite mass but not a definite volume.it has a definite volume but not a definite shape.it has a definite shape but not a definite volume.
