RALPH IN THE TUB (shudder)
fall
The level will fall: the metal in the boat forces the boat to sink lower in the water, displacing water not only for the bolts, but for the air in the hull at water level. if the bolts are allowed to sink, they displace less volume than they did in the boat
AIRLINER
low density air (approaching vacuum) acts as a good insulator not allowing heat of plane to be dissipated?
The air conditioners are needed to cool off the cabin because the body heat of every body in the plane. The o-zone layer at the high altitude less affects the U.V. rays striking the fuselage. Also, the friction generated as the plane rips trough the air at 600 knots does more to heat the plane than cool it.(try going down into the cargo hold in a 747 at 30,000 feet and see if you want to stay there for long).
EXPANSION
ice - to threaten ships with icebergs that would otherwise sink.
Water expands below 3.98°C down to 0°C Otherwise ice would be heavier than water, with catastrophic consequences. Lakes and ocean's would freeze from the bottom up killing all life.
PIPES
10h 40m
Code:
Let V= volume of water in pond
Let P = volume drained by one large pipe in one hour
Let p = volume drianed by one small pipe in one hour
Let t = time
V - 9P*8 = 0 V-6*p*(16) = 0
+(-V+6p*16 = 0) V = 6*p*16
-9P*8+6p*16 = 0
9P*8 = 6p*16 V-3(P)(t)-5(p)(t) = 0
P = 1.33p --------------> 6p*16-3(1.33p)(t)-5(p)(t) = 0
96p-4pt-5pt = 0
96p = 9pt
t = (96p)/(9p)
t = 10.667 hrs = 10 hrs 40 min
Your come back gathers pace.

Airplane: The friction created by the speed would increase the heat. Planes during WWII were cold because they were not traveling as fast)
expansion: only thing I can think of is ice.

The boat..............water will fall. The cargo will push the boat further into the water displacing not only the volume of the cargo but also the volume of the air in the cargo hold. if the cargo is allowed to sink it no longer displaces the air in the hold
airplane....... closer to sun = more heat (thinner atmosphere)
body heat of 300 people
friction
heat generated by engines warms air slightly (Hummm, but not in the cabin)
"If water expanded during heat, then plants would explode when they got warm"
"Water in plant tissue turns to ice and expands thus causing plant cells to explode/rupture."
Is that ?'Design' or ?'Evolution'?

I am deeply distressed to hear about your medical condition
. May I suggest gargling with salt water, and floss, always floss.
If you take your mechanical watch to the mountains, will it run faster or more slowly than usual
How would you make a raw egg float halfway between the surface and the bottom of a glass of water
An ice cube is floating in a beaker of water, with the entire system at 0º Centigrade (32ºF). Just enough heat is applied to melt the ice cube without raising the temperature of the system. What happens to the water level in the beaker?
Does it rise, fall, or stay the same
