    The answer to this question really depends on three things: 1. How much water you have 2. How cold it is to start out 3.How cold the things around it are. Water actually freezes when it gets to 32 degrees Fahrenheit (0 degrees Celsius), but the time it takes to get there may be different. (這部份包含有關題目的三個問題_)

    Let's start with the first. If you take two glasses, and fill one with a tiny bit of water, and the other about halfway, then put them both in the freezer, the one with less water will freeze first (you can try this at home, but I recommend using plastic cups and not glass ones). (這部份是第一題的答案和做法)

    Now let's move on to the second part. Let's say you have two glasses, and you fill one with really cold water that has been in the refrigerator, and the other with really hot water from the sink. If you put both of them in the freezer, the one that started out colder will freeze first. (這部份是第二題的答案和做法)

    For the third part, let's imagine that you have two glasses with the same amount of water in them, and the water is at the same temperature. Imagine putting one outside on a really really cold day in Georgia, and having a friend in Alaska put one outside on the same day. Since it would be so much colder in Alaska, the glass of water there would freeze before yours. (這部份是第三題的答案和做法)

    So, if you took a tiny bit of really cold water in a glass, and put it outside on a cold day in Alaska, it would freeze a lot faster than a big glass of hot water outside on a cold day in Georgia. (結論)
