If the ice is floating (North Pole), then water levels do NOT rise when the ice melts.
If the ice is on land (Alaska, Greenland, Antarctica) then the ice melting will cause sea levels to rise.
Surprisingly, no. Water is one of the few substances that expands as it freezes. So as ice melts in a cup of water, the water level actually lowers. You can test this by filling a cup of ice water to the brim, and leaving it standing for a few hours. You'll find that the water has not spilled over the top.
If you measure the water level before adding the ice, the level will increase. If you measure the water level after adding ice, there might be a slight increase, but not much after it melts.
It will not be any change in water.

Because there is more water in a bucket than in a cup, and more energy has to be put into the bucket of water than the little cup of water to bring them to the same temperature.
Salt affects how fast ice melts in a cup of water. When you add salt, the melting process will be faster but it will only affect the part of the ice cube that comes into contact with salt.
No, it wouldn't. a sugar cube would melt a lot faster in a cup of Hot water. the hot water helps it desolve more evenly than cold water.
Water expands slightly when it freezes, so 1 cup of ice will be a little less when it turns back to water, but it is only a small change in volume, and for a rough measurement like a cupful it will hardly be noticeable
the hottter the temperature the faster salt dissolves
Yes, the water has turned into ice. It was a liquid but it is now a solid. You can change it back again by melting it.
They are both one cup. The water weighs more though.
A cup of boiling water since it has higher temperature. Note that heat transfer depends more on the temperature.
No.You can boil water in a paper cup over a flame although you'll have more success if you have a steel grid in between so that the paper is heated evenly. The temperature at which paper burns is lower than that at which water boils so that the water keeps the paper too cool to catch light.If you try the same with a styrofoam cup, it will melt. Because styrofoam is a good insulator, the water can't keep it cool enough to prevent it melting.
tap water
a cup of water that is boiled since it gives more heat.
Because there is more water in a bucket than in a cup, and more energy has to be put into the bucket of water than the little cup of water to bring them to the same temperature.
yes a plant can grow in a cup of water unless you put some tissue in the cup to squeeze the seed in to having more water which provides them more nutrition
The cup.
The cup.
James wants to find out whether a cup of salt water or a cup of fresh water will freeze more quickly. What is the best way for him to determine this
I'd have to say yes if the cup is in sunlight for example. Just like when you wear different colored shirts outside. A darker cup will absorb more light, and a lighter cup will reflect more light. The light energy converts into heat energy. Therefore, a darker colored cup would make water get warmer faster in light.
