Introduction
Temperature is a crucial aspect of our daily lives, and understanding how it changes over time is essential in various fields, including meteorology, engineering, and environmental science. In this article, we will explore a word problem that involves calculating the change in temperature over a three-hour period. We will write and solve an equation to demonstrate our answer.
The Problem
The air temperature at 9 a.m. is -5.8 degrees Celsius. The air temperature at noon is -1.6 degrees Celsius. What is the change in temperature during these three hours?
Step 1: Define the Variables
Let's define the variables:
- T1: The initial temperature at 9 a.m. (in degrees Celsius)
- T2: The final temperature at noon (in degrees Celsius)
- ΔT: The change in temperature (in degrees Celsius)
Step 2: Write the Equation
The change in temperature (ΔT) is equal to the difference between the final temperature (T2) and the initial temperature (T1). We can write this as:
ΔT = T2 - T1
Step 3: Plug in the Values
We are given the values of T1 and T2:
T1 = -5.8°C (at 9 a.m.) T2 = -1.6°C (at noon)
Substituting these values into the equation, we get:
ΔT = -1.6°C - (-5.8°C)
Step 4: Simplify the Equation
To simplify the equation, we need to combine the negative terms:
ΔT = -1.6°C + 5.8°C
Step 5: Calculate the Change in Temperature
Now, we can calculate the change in temperature:
ΔT = 4.2°C
Conclusion
In this article, we have solved a word problem involving the change in temperature over a three-hour period. We have written and solved an equation to demonstrate our answer. The change in temperature is 4.2°C, which means that the temperature increased by 4.2°C from 9 a.m. to noon.
