Question 9 of 18intermediate🔧 ApplyDiagram4 marks

The temperature variation over two days in Jodhpur, Rajasthan, is given below. Draw a double-bar graph. Use the scale 1 unit = 4°C. Can you guess which two months these days might belong to?

Correct Answer

Draw a double bar graph with time (12am, 3am, 6am, 9am, 12pm, 3pm, 6pm, 9pm) on the x-axis and temperature on the y-axis using scale 1 unit = 4°C. Day 1 shows mild temperatures (16-34°C) suggesting winter months like December-January. Day 2 shows high temperatures (30-43°C) suggesting summer months like May-June.

Explanation

Day 1 temperatures range from 16°C to 34°C, which is typical of winter in Rajasthan. Day 2 temperatures range from 30°C to 43°C, which is typical of summer. The contrast suggests these could be from different seasons - winter (December-January) and summer (May-June).

Solution Steps

  1. Step 1: Set up axes with time on x-axis and temperature on y-axis

  2. Step 2: Use scale 1 unit = 4°C on y-axis

  3. Step 3: Plot Day 1 temperatures: 20, 18, 16, 20, 26, 34, 30, 24

  4. Step 4: Plot Day 2 temperatures: 37, 34, 30, 33, 37, 43, 42, 39

  5. Step 5: Draw bars for each time with different colors for Day 1 and Day 2

  6. Step 6: Analyze: Day 1 shows winter pattern, Day 2 shows summer pattern
