The molar heat of vaporization for liquid water is 40.6 kJ/mole. How much energy is required to change 7.0 g of liquid water to steam if the water is already at 100°C?

h let me think

law of conservation of matter

c- cold periods in earth's history during which glaciers covered much of the surface.

explanation:

question: ray weighs 100 kilograms, his wrestling partner, bobby, weighs 50 kilograms. if ray moves at 4 m s , how fast will bobby have to run at him to apply an equal amount of kinetic energy?

answer: 8 m/s he needs to run twice as fast to keep up so he has some work to do

explanation:   if the mass has units of kilograms and the velocity of meters per second, the kinetic energy has units of kilograms-meters squared per second squared.
