A temperature difference of 5K is equal to: a) a difference of 12 on the Celsius scale. b) a difference of 9 on the Fahrenheit scale. c) a difference of 2.8 on the Fahrenheit scale. d) a difference of 32.5 on the Fahrenheit scale.<\/p>\n\n\n\n

The Correct Answer and Explanation is:<\/mark><\/strong><\/p>\n\n\n\n

Correct Answer: b) a difference of 9 on the Fahrenheit scale.<\/strong><\/p>\n\n\n\n

\n\n\n\n

Explanation:<\/strong><\/h3>\n\n\n\n

To understand how temperature differences relate across various scales, it\u2019s essential to remember that Kelvin (K)<\/strong> and Celsius (\u00b0C)<\/strong> use the same size<\/em> unit. This means:<\/p>\n\n\n\n

\n

A difference of 1 K = a difference of 1 \u00b0C<\/strong><\/p>\n<\/blockquote>\n\n\n\n

So, a difference of 5 K = difference of 5 \u00b0C<\/strong>.<\/p>\n\n\n\n

Now, to convert a temperature difference<\/strong> from Celsius to Fahrenheit<\/strong>, we do not use the normal temperature conversion formula<\/strong>, which includes addition or subtraction. Instead, we convert differences<\/strong> using only the scaling factor<\/strong>, which is 1.8 (or 9\/5)<\/strong>.<\/p>\n\n\n\n

\n\n\n\n

Formula for Converting Temperature Difference:<\/strong><\/h3>\n\n\n\n

\u0394\u00b0F=\u0394\u00b0C\u00d795\\Delta\u00b0F = \\Delta\u00b0C \\times \\frac{9}{5}\u0394\u00b0F=\u0394\u00b0C\u00d759\u200b\u0394\u00b0F=5\u00b0C\u00d795=9\u00b0F\\Delta\u00b0F = 5\u00b0C \\times \\frac{9}{5} = 9\u00b0F\u0394\u00b0F=5\u00b0C\u00d759\u200b=9\u00b0F<\/p>\n\n\n\n

\n\n\n\n

So, a temperature difference of 5 Kelvin<\/strong> is:<\/p>\n\n\n\n

    \n
  • A difference of 5\u00b0C<\/strong>, because Kelvin and Celsius scale differences are equivalent.<\/li>\n\n\n\n
  • A difference of 9\u00b0F<\/strong>, because 5\u00d795=95 \u00d7 \\frac{9}{5} = 95\u00d759\u200b=9.<\/li>\n<\/ul>\n\n\n\n
    \n\n\n\n

    Summary of Choices:<\/strong><\/h3>\n\n\n\n
    Choice<\/th>Meaning<\/th>Correct?<\/th><\/tr><\/thead>
    a) 12\u00b0C<\/td>Incorrect (5 K = 5\u00b0C)<\/td>\u274c<\/td><\/tr>
    b) 9\u00b0F<\/td>Correct (5\u00b0C \u00d7 9\/5 = 9\u00b0F)<\/td>\u2705<\/td><\/tr>
    c) 2.8\u00b0F<\/td>Incorrect (confused with conversion between \u00b0C and K values, not differences)<\/td>\u274c<\/td><\/tr>
    d) 32.5\u00b0F<\/td>Incorrect (might be confused with freezing point diff, not scale difference)<\/td>\u274c<\/td><\/tr><\/tbody><\/table><\/figure>\n\n\n\n
    \n\n\n\n

    Conclusion:<\/strong><\/h3>\n\n\n\n

    The correct answer is b) a difference of 9 on the Fahrenheit scale<\/strong>. This demonstrates the importance of knowing that while temperature values<\/strong> and temperature differences<\/strong> are related, they are converted differently across scales<\/strong>.<\/p>\n\n\n\n
