it expands because water when it freezes becomes ice and ice expands in cold temperatures. Take a soda can for example put it in the freezer for about 20 min. it should have expanded by then.
THANKS!
1/2 a cup of water
paper
Water expands when it freezes.
no.
While is SOUNDS impossible, yes. you can- under the right circumstances. It requiress an exact balance between an even source of heat, and the wetting of the bag. Heat keeps the paper from getting too mushy, water keeps the paper from catching fire. This has been used for years as a Boy Scout camping entertainment. Not suggested that you try it indoors- parts of the bag above the waterline catch fire, and sometimes the bag comes apart.
what you think happens to the frazen cup of water tat melts will it be the same amount of water as originally had
It goes into the cup.
If you mean *exactly* one cup by volume, you have the iceberg scenario. The cup of frozen water will be less dense, so it will weigh less. If you just freeze a cup of water, don't spill any, and *don't* trim the excess to bring the volume back to exactly one cup, then it will weigh exactly what it did at room temp.
yes, this is why if you put a filled to the brim cup of water in the freezer, it overflows when it is frozen....
A paper cup typically does not keep water hotter than a plastic cup. Paper is a poor insulator compared to plastic, so heat is more likely to escape from a paper cup, leading to faster cooling of the water inside.
The boiling point of water is 100 degrees. However, the point at which paper burns is much higher than 100 degrees. When you boil water in a paper cup, all of the heat is transferred to the water, not the cup. When the water starts to boil, the paper stays unburnt. After the water has boiled through, there should be a small black mark on the base of the cup which can be easily removed.
Yes. It doesn't matter if it is frozen. Just cup your hands and then pour water into it.
A paper cup can be used to boil water by filling it with water and placing it directly over a heat source such as a stove or campfire. The water will boil due to the heat transfer from the flame to the paper cup, causing the water to reach its boiling point. The paper will char and may eventually catch fire, so this method should be done with caution.
Yes, frozen yogurt or fro-yo is made from yogurt and other dairy products. It is said to be low in fat, because it uses milk instead of cream. This is why frozen yogurt really is a healthier alternative to ice cream. And its tart flavor tastes really good! When you're buying frozen yogurt, be sure to keep it fresh in an eco-friendly yogurt paper cup. This yogurt cup from CupDepot is made from double poly lined paper so you can be sure it's spill-proof.

the paper cup cannot become appreciably hotter than the water it contains
1) This is what you'll need... paper cup(s) ,water or a faucet , rocks (small and medium sized), and a freezer. 2) First, fill your paper cup with 2 cm. or less than an inch of sand. 3) Next, put abut 1 or 2(or as desired) rocks in the sand inside of the cup. 4) Then, fill the paper cup three fourths of the way to he top of paper cup. 5) Last, put cup in freezer. 6) If you want to make it a lesson, you peel the paper cup off after it is frozen and rub it on a bar of soap and have them tell/write about what the glacier does to land (soap) or customize what you want them to write.
The boiling point of water is just 100 deg celcius. But the ignition temperature for paper would be higher than 200 deg celcius. So when paper cup filled with water it cannot attain temperature higher than 100 deg. Hence no burning becomes possible
