Understanding Temperature Graphs

The video tutorial explains how to interpret a graph representing temperature changes over time. It introduces the problem, defines variables for temperature and time, and guides viewers through identifying the y-intercept. The tutorial also covers positive and negative intervals and analyzes temperature changes throughout the day, helping students understand how to read and interpret graphs in the context of temperature data.

What does the capital T represent in the context of the graph?

• Temperature in degrees Fahrenheit

• Temperature in degrees Celsius

• Time in hours after midnight

• Total time elapsed

If the time is 4 hours after midnight, what is the standard time?

• 4:00 PM

• 2:00 PM

• 2:00 AM

• 4:00 AM

What is the significance of the y-intercept in the temperature graph?

• It shows the highest temperature of the day

• It indicates the temperature at the start of the day

• It represents the average temperature

• It marks the time when the temperature is zero

At what temperature does the y-intercept occur in the graph?

• 0 degrees Celsius

• -3 degrees Celsius

• 3 degrees Celsius

• -5 degrees Celsius

When is the temperature considered positive on the graph?

• When it is decreasing

• When it is exactly zero

• When it is above zero

• When it is below zero

During which time period was the temperature above zero?

• Between 6 AM and 6 PM

• Between 4 AM and 4 PM

• Between 8 AM and 8 PM

• Between 2 AM and 2 PM

What does an increasing trend in the graph indicate about the temperature?

• The temperature is fluctuating

• The temperature is constant

• The temperature is getting warmer

• The temperature is getting colder

Between which times did the temperature increase?

• 2 AM to 2 PM

• 6 AM to 6 PM

• 8 AM to 8 PM

• 4 AM to 4 PM

What does a decreasing trend in the graph signify?

• The temperature is stable

• The temperature is unpredictable

• The temperature is falling

• The temperature is rising

How can you tell if the temperature is getting warmer from the graph?

• The graph is moving downwards

• The graph is zigzagging

• The graph is moving upwards

• The graph is flat
