Form 5: Temperature Changes Over Time

Analyze temperature changes over time using linear graphs and rates of change. Determine hourly or daily temperature variations.

Questions

  1. MultiChoice

    A graph shows temperature (°C) over time (hours) going through (0, 0) and (4, 12). What is the heating rate?

  2. MultiChoice

    A cooling liquid drops from 20°C to 10°C in 5 minutes. What is the rate of temperature change?

  3. MultiChoice

    What does a positive slope represent on a temperature vs time graph?

  4. MultiChoice

    What does a negative slope represent on a temperature vs time graph?

  5. MultiChoice

    A room stays at a constant 70°F for 6 hours. What is the slope of the temperature-time graph?

  6. MultiChoice

    At 2 PM the temperature is 50°F and at 6 PM it is 66°F. What is the hourly rate of temperature change?

  7. MultiChoice
