A student places a closed black metal container full of water on a sunny windowsill. After one hour, the water temperature rises, and when the student shakes the container, the water moves faster inside than before.
Which statement BEST explains what happened?
Light energy was absorbed by the container, converted to thermal energy, and increased particle motion in the water.
Which MOST likely represents convection? A.) A pan handle warming up B.) Air circulating in a heated room
Air circulating in a heated room

More kinetic Energy
Kinetic energy depends only on speed.
True or False
False: Mass and Speed
