Water can be thought to be made up of millions of tiny little particles. These tiny particles are constantly moving. At higher temperatures, particles have more energy and they move faster. Given below is water at different temperatures. In which one will the particles of water be moving the fastest? (1 Point)
a. Water at 25°
b. Water at 60°
c. Ice
d. steam

Consider a u-tube whose arms are open to the atmosphere. now equal volumes of water and light oil (ρ = 49.3 lbm/ft3) are poured from different arms. a person blows from the oil side of the u-tube until the contact surface of the two fluids moves to the bottom of the u-tube, and therefore, the liquid levels in the two arms are the same. if the fluid height in each arm is 30 in, determine the gage pressure exerted by the person on the oil by blowing.
