How does aluminum foil keep some objects warmer and colder then plastic wrap?
A paper towel transfers heat at a much lower rate than plastic wrap or aluminum foil. A paper towel or two wrapped completely around the item(s,) so that air is sealed fairly well, is your ticket!!
Will coca cola dissolve a rib bone?
Eventually, it will. Eventually, Coca Cola will actually dissolve anything, but this could take a really long time. Especially since it's a rib bone :) You could try a tooth
Teeth, are smaller and more fragile, so they dissolve fairly quickly
Does water boil faster in a bigger pot than in a smaller pot at the same temperature?
There are some conditions that can turn the result either way, but probably it will boil faster in the bigger pot. The bigger pot offers a greater surface for heat transfer, so it should boil faster there.
All food has calories. Popcorn is very low in calories, high in fiber. Few people have ever gotten fat on popcorn, unless they cook it in high oil and drown it in butter. The high levels of salt often found can also cause problems.
What effect did the popularity of the television have on popcorn?
people buy more popcorn because its delicious and amazing and people eat it when they got
to see a movie.
Is food coloring a mechanical mixture or solution?
It is a solution because Tartrazine, and Brilliant Blue FCF are both water soluble. As you might already know a solution has a Solute, the colouring, and a solvent the h2o.

What is a good hypothesis for a banana science project?
Banana's rections to oxygen. :D we're studying that right now.
What type of bread molds faster?
whole wheat or white bread im trying to do my science fair project and i looked up that it can be whole wheat or white bread
What liquids dissolves the candy Sweet tarts?
if u stick it in your mouth spit is what can dissolve it and any other kind of liquid pop would really work it might take though more then a couple min. but all liquids would dissolve it though
Which light bulb melts chocolate the fastest?
Sunlight melts chocolate faster because the rays contain Ultra Violet.
two bananas, a counter, a fridge, and some time.
What is the Hypothesis of potato battery?
do you mean 'who is the principal of the school of potato batteries?'
What happens when an egg is soaked in Gatorade?
If you put the egg in vinegar then put it into Gatorade then the egg looks defalated, red, and very sticky.
How can a potato light a light bulb?
The potato contains phosphoric acid, and this acid, when placed between two electrodes (one of copper and one of zinc) will product a small voltage. This is a simple electrochemical cell (a battery). Make several and connect them in series to increase the voltage, and with this setup, an investigator can light a light bulb.
Using several potatoes and strips of zinc and copper, make the cells. Copper wire and galvanized nails (which are coated with zinc) will make good electrodes. There are a number of sites on the web to review how it's done. YouTube even posts some good short vids on these handy science projects.
Why do you get a bigger eruption with diet coke and mentos?
It doesn't. However, most geyser-makers prefer diet soda over regular because the sugar substitute is not sticky (sugar, of course, is very sticky) and therefore does not make as much of a mess for the ones standing nearby or cleaning up after! out during the explosion.
Answer:when i tried to see if coke or Pepsi max would Not necessarily The reason for the geyser is not a chemical reactionause the diet soda doesn't have nearly as sticky residue if not cleaned up properly.Because it has less sugar.
Does light affect the rate of bananas spoiling?
I heard that milk in an opaque carton will spoil slowly, whereas milk in a translucent plastic jug (as most is) spoils more quickly. Supposedly, the light spoils the milk.
Sounded good at first, then I thought about it a little bit. The milk is rarely exposed to light, at least once I buy it. The light in the fridge turns off when I close the door. So how can a few moments' of exposure make that big of a difference? Unless it's the exposure at the store that's supposed to make the difference?
I'd like to see other people's answers, but my first guess is no.
What is the difference between a fresh water fish and a salt water fish?
The primary difference would be in the salinity of the the water which in turn changes the ecosystem and supports different life forms. Both will support a different variety of fish and wildlife and can thrive in the proper environment.
Where can I find out how food wrapping affects spoilage?
Some sources say that plastic and other wrappings actually speed up spoilage because they hold in air, but for the most part packaging slows food spoilage. The functions of packaging include acting as a barrier against microbial, physical and chemical protection.
Physical: - e.g. cardboard stops bruising of fruits, therefore preventing enzymic degradation of the flesh.
Microbial: Perhaps the most important aspect of food preservation. Packaging such as plastic or metal can prevent the entry and growth of microorganisms that break down food components and cause off smells and bad textures. For example, plastic wrapping over a half-eaten steak prevents entry of microbes that break down proteins and fats.
Chemical: Light and oxygen can causes damage to food by increasing the incidence of rancidity (e.g. autooxidation [fat breakdown]) and vitamin degradation (for example riboflavin in milk breaks down it the presence of sunlight). This is why most milk bottles are opaque and gas-impermeable, which means Oxygen can't come in. Another example is cellulose film wrapping of bread, which prevents staling by stopping sntry of oxygen.
What is caramelization give the importance of this process?
Hi, I had trouble with this too. I hope the following Information helps.
Caramelisation is a complex, poorly understood process that produces hundreds of chemicals. Here is an overview: # # equilibration of anomeric and ring forms # sucrose inversion to fructose and glucose # condensation # intramolecular bonding # isomerization of aldoses to ketoses # dehydration reactions # fragmentation reactions # unsaturated polymer formationCaramelisation should not be confused with the Maillard reaction, in which a reducing sugar reacts with amino acids.

Is humus an element compound or mixture?
No. Humus is the Turkish spelling of the Middle Eastern dish whose preferred spelling is hommos, houmos, or hummus. The dish involves the cooking or mashing of chickpeas, for serving with garlic, ground sesame seeds, lemon juice, olive oil, and salt. The preferred use of the word humus is its reference to dark brown, fresh-smelling, organic matter-rich soil. It isn't an element. But it contains some of the 16-17 nutrients that are necessary for plant and soil health.
What soft drinks spew the same amount?
This is a scientific test based on the level of carbonation in various retail sodas. This will vary by product, packaging, and temperature, so it is difficult to make small distinctions.
Why does water dissolve Jolly Ranchers the fastest?
Most commonly corn syrup is used to make hard candies. For the corn syrup crystalline state to go back into solution again just takes water. Common vinegar is about 95% water. The acidity of vinegar also helps. Corn syrup is made from corn starch by an acid hydrolysis process; it was soluble in an acid solution.
Where can you buy brine shrimp eggs?
Brine shrimp are commonly found in the saltiest bodies of water, that hardly any predators or prey could survive other than the brine shrimp. They could be hunted and found in about 250 places in the world, only because of the certain amount of salty lakes and oceans there are makes it harder and harder to find this species. Another name for this marine creature is artimiea.
