How does the body shape of marine mammals help them?
The shape reduces drag when in water, allowing the animal to propel itself most efficiently.
What material prevent heat loss most efficiently?
styro
How does the shape of the container affect the freezing rate of water?
The amount of water in a container will affect how fast it heats up. If there is a small amount of water in a container the water will biol/heat faster. However, if there is a big amount of water it will take longer for the heat to reach all parts of the water resulting in a longer time for the water to boil/heat
What substance melts ice most efficiently sugar salt pepper or artificial sweetener?
== == Salt lowers the freezing point of water by 32 degrees. If salt is sprinkled onto ice, it causes the ice to melt by a heat transfer. Out of the substances listed, salt would melt ice most efficiently.
What is the most efficient geometrical shape?
We cannot assess the efficiency of a geometrical shape unless we have a particular purpose in mind. You will have to state what you wish to efficiently do, by means of a geometrical figure.
When we heat a water in a pan by which mode does most of the heat travel in water?
Radiation
What is the most effective shape for a rocket?
A teardrop is the most aerodynamically effective shape for a rocket travelling through the atmosphere. From an engineering standpoint, a cylindrical shape accommodates compressed gas cylinders (fuel and oxygen) most efficiently. For a rocket operating outside the atmosphere, shape is irrelevant because it will not encounter drag no matter how un-aerodynamic the shape.
What shape holds the most heat?
Aluminum
What phase is water most dense in?
Water is most dense in the heat or hotness
Why does water lose the most heat when its just stopped being heated?
water loses it's most heat because the stored in the water gets out in steam.
Which blinds block the sun most efficiently?
These shades effectively block heat and glare. This revolutionary fabric, manufactured by Phifer, allows more light and heat to penetrate through, them ideal
Why lithium use as heat transfer agent in nuclear reactors?
Its not used in any reactor designs. Most use ordinary water. A few designs use molten metals like sodium, NaK (sodium-potassium alloy), mercury, etc. because they do not slow the neutrons as water would and they want fast neutrons in these designs. These metals also transfer heat more efficiently than water does.
