A sample of 2.50 kg of water is held at a temperature of 100°C. How much energy must be added to completely turn the liquid water to water vapor?
(The latent heat of vaporization for water is 2260 kJ/kg; the latent heat of
fusion for water is 333 kJ/kg.)
O A. 833 kJ
B. 904 kJ
C. 5650 kJ
O D. 133 kJ

What is the rate of 12 liters of water moving through a water hose in 4.0 minutes?

On a horizontal frictionless surface, a small block with mass 0.200 kg has a collision with a block of mass 0.400 kg. immediately after the collision, the 0.200 kg block is moving at 12.0 m/s in the direction 30° north of east and the 0.400 kg block is moving at 11.2 m/s in the direction 53.1° south of east. use coordinates where the +x-axis is east and the +y-axis is north.(a) what is the total kinetic energy of the two blocks after the collision (in ) what is the x-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your ) what is the y-component of the total momentum of the two blocks after the collision? (indicate the direction with the sign of your answer.)
