Q. 1.24 - An Introduction to General, Organic, and Biological Chemistry

Question

a. What is measured on the horizontal axis?

b. What is the range of value on the horizontal axis?

c. What is the temperature of the tea after $20$ min?

d. How many minutes were needed to reach a temperature of $45°C$ ?

Step-by-Step Solution

Answer

a. The time is measured in min, on the horizontal axis.

b. The range of value on the horizontal axis is $0‐98$ min.

c. The temperature of the tea after $20$min is $56 C$.

d. $40$minutes were needed to reach a temperature of  $45°C$.

Part (a) step 1: Given Information

We need to find measured on the horizontal axis.

Part (a) step 2: Explanation

On the horizontal axis, the time is measured in min.

Part (b) step 1: Given Information

We need to find the range of value on the horizontal axis.

Part (b) step 2: Explanation

From the graph is understand the range of time is $0‐98$ min.

Part (c) step 1: Given Information

We need to find the temperature of the tea after $20$min.

Part (c) step 2: Explanation

From the graph is understand the temperature after $20$ min is $56 C$.

Part (d) step 1: Given Information

We need to find how many minutes were needed to reach a temperature of  $45 °C$.

Part (d) step 2: Explanation

We need $40$ min to reach $45°C$, from the graph.
