Unit 9: Time and Again
In her chemistry lab class, Reena heated a liquid until it
boiled. After a while she measured the temperature of the
liquid as it cooled down. The following table shows its
temperature, in c (degree Celsius), in t (minutes after it
boiled).

Reena believes that the relation between cand tis modelled by a linear equation
c* -2.241 +105,0 SIS 20
The teacher observed Reena and was impressed with her work and efforts.
To test Reena on the basis of her understanding and thoroughness of her work, the teacher asked her
the following questions,
Can you help Reena with her answers?
9.1 In your opinion, what are the independent and dependent variables in this scenario?
What is the boiling temperature of the liquid?
If the liquid freezes al 26.6 C, then at what time will it freeze assuming that Reena started the
experiment at 10.00 am.
Let's learn how experiments work
