Temperature Difference Concepts

This video tutorial explains how to find the difference between temperatures using two methods: a thermometer and a calculation-based approach. The thermometer method involves understanding the graduation of the thermometer, while the calculation method uses rules for same and different signs. The video provides examples and practice questions to reinforce learning.

What are the possible combinations of temperature signs discussed in the video?

• All of the above

• One positive and one negative temperature

• Two negative temperatures

• Two positive temperatures

What is the first step in using a thermometer to find the difference between two temperatures?

• Identify the temperatures

• Subtract the temperatures

• Understand the thermometer's graduation

• Add the temperatures

How do you determine the graduation of a thermometer?

• By measuring the length of the thermometer

• By comparing with another thermometer

• By checking the temperature range

• By counting the lines between whole numbers

What is the difference between 6°C and 14°C using a thermometer?

• 12 degrees

• 6 degrees

• 10 degrees

• 8 degrees

What is the basic rule for finding the difference between temperatures with the same sign?

• Add the temperatures

• Subtract the smaller from the larger

• Multiply the temperatures

• Divide the larger by the smaller

How do you find the difference between temperatures with different signs?

• Subtract the smaller from the larger

• Add the absolute values

• Multiply the temperatures

• Divide the larger by the smaller

What is the difference between -10°C and 2°C using the calculation method?

• 14 degrees

• 10 degrees

• 8 degrees

• 12 degrees

What is the difference between -40°F and -20°F?

• 40 degrees

• 30 degrees

• 20 degrees

• 10 degrees

What is the difference between 7°C and -17°C?

• 20 degrees

• 24 degrees

• 34 degrees

• 30 degrees

What is the difference between -11°F and -11°F?

• 22 degrees

• 11 degrees

• 0 degrees

• 33 degrees
