A student learns that evaporation can occur when water from Earth's surface becomes water vapor and enters the atmosphere. What is needed for the evaporation to take place? Kinetic energy Light Energy from the Sun
Heat Energy from the Sun
Energy from the wind

If the speed of a particle triples ,by what factor does its kinetic energy increase?

Consider an ordinary, helium-filled party balloon with a volume of 2.2 ft3. the lifting force on the balloon due to the outside air is the net resultant of the pressure distribution exerted on the exterior surface of the balloon. using this fact, we can derive archimedes’ principle, namely that the upward force on the balloon is equal to the weight of the air displaced by the balloon. assuming that the balloon is at sea level, where the air density is 0.002377 slug/ft3, calculate the maximum weight that can be lifted by the balloon. note: the molecular weight of air is 28.8 and that of helium is 4.

Explain what happens at the saturation point when adding salt to water at room temperature.
