請根據(jù)下面的內(nèi)容提示，用英語寫一篇物理實驗報告。

實驗?zāi)康模鹤C明冰融化過程中溫度不變

實驗用品：冰塊，大小燒杯，溫度計，熱水

實驗步驟：1.在一個大燒杯中倒入熱水；

2．把裝有冰塊的小燒杯置入熱水中，在冰塊中插入溫度計；

3．觀察冰塊溫度變化，注意冰融化開始時的溫度；

4．觀察冰融化為水過程中的溫度變化。

實驗結(jié)果：冰全部融化為水融化過程中溫度不變。

實驗結(jié)論：冰在零攝氏度時才開始融化，融化過程中溫度不變。

注意：1.詞數(shù)：100左右；

2．可適當增加細節(jié)，以使行文連貫；

3．參考詞匯：燒杯beaker；溫度計thermometer；觀察observe。

Today I’d like to tell you anything about riding a bike in Wuhan.If you visit Wuhan，you’ll see many buses，cars and also bikes.It’s very cheap to use bike.If you take a bus，you often have to wait for half an hour or so.What’s more，the buses move very slow and are quite crowded.I was used to go to the stadium by bus.I often arrived there late，feeling tiring.Then a friend suggested I went to the training classes by bike.I accepted his advice.Take a bus takes 30 minutes，while riding a bike takes 15 minutes.It is not out of date at all.Instead，I love riding to attend the classes but in this way I feel more better.
