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 c and t is modelled by a linear equation.c = -2.24t + 105, 0 ≤ t ≤ 20The 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?Q1. In your opinion, what are the dependent and independent variables in this scenario?Q2. What is the boiling temperature of the liquid?Q3. If the liquid freezes at 26.6oC, then at what time will it freeze assuming that Reena started the experiment at 10:00 a.m? |
