Question

At sunset the temperature was 4 dgrees. the next morning at sunset it was -7 degrees. what is the difference betweeen these temperatures/

Answer 1

The difference between these temperatures for the sunset is found as 11 degrees.

What is temperature difference?

In science, the term Delta T (ΔT) refers to the temperature between two measuring points. The temperature varies according to time and/or location.

Some key features regarding the temperature difference are-

• Merus, for example, uses it to assess the effectiveness of such a heat exchanger.
• Or to evaluate the effectiveness of a heating or cooling system.
• A fourth letter of a Greek alphabet is, (Δ). Whereas is the capital letter symbol and the lower case letter.
• The sign is also used in mathematics. Describes the "difference" between any two changeable quantities. T is a value in a process that represents a difference between two observed temperatures.

Now, according to the question;

Let the initial temperature be 'T' = 4 degrees.

Let the final temperature be 't' = -7 degrees.

Therefore, the temperature difference is;

ΔT =  T - t

     = 4 - (-7)

     = 4 + 7

ΔT = 11

Therefore, the difference between these temperatures is 11 degrees.
