Q8. Sara took some ice in a beaker and heated it. She recorded the changes in temperature using a
thermometer and had the following observations:
Time (in min.). Temp. (in C)
0 -3
1 -1
2 0
3 0
4 5
5 8
6 12
7 15
8 19
10 22
15 30
20 50
25 73
30 100
35 100
Based on the above observations, answer the following questions:
a. State the change observed between 2-3 minutes and name the process involved.
b. The temperature remains constant between 30-35 min, what could be the reason for this? Name the heat involved in this process and define it.
