An ice chest at a beach party contains 12 cans of soda at 4.05 °c. each can of soda has a mass of 0.35 kg and a specific heat capacity of 3800 j/(kg c°). someone adds a 6.21-kg watermelon at 24.0 °c to the chest. the specific heat capacity of watermelon is nearly the same as that of water. ignore the specific heat capacity of the chest and determine the final temperature t of the soda and watermelon in degrees celsius.

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.
