If a thermometer is currently reading 42.5 \u00c2\u00b0F, what is the temperature in Kelvin? Note: Tc = 5\/9(TF – 32)<\/p>\n\n\n\n

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

To convert a temperature from Fahrenheit (\u00b0F) to Kelvin (K), we need to first convert the temperature to Celsius (\u00b0C) and then convert the Celsius value to Kelvin. The formulas for these conversions are as follows:<\/p>\n\n\n\n

    \n
  1. Fahrenheit to Celsius<\/strong>:
    Tc=59(TF\u221232)T_c = \\frac{5}{9}(T_F – 32)Tc\u200b=95\u200b(TF\u200b\u221232)
    where TFT_FTF\u200b is the temperature in Fahrenheit, and TcT_cTc\u200b is the temperature in Celsius.<\/li>\n\n\n\n
  2. Celsius to Kelvin<\/strong>:
    TK=Tc+273.15T_K = T_c + 273.15TK\u200b=Tc\u200b+273.15
    where TKT_KTK\u200b is the temperature in Kelvin, and TcT_cTc\u200b is the temperature in Celsius.<\/li>\n<\/ol>\n\n\n\n

    Now, let’s calculate the temperature in Kelvin for a thermometer reading of 42.5\u00b0F.<\/p>\n\n\n\n

    Step 1: Convert 42.5\u00b0F to Celsius<\/h3>\n\n\n\n

    Using the formula:Tc=59(42.5\u221232)T_c = \\frac{5}{9}(42.5 – 32)Tc\u200b=95\u200b(42.5\u221232)<\/p>\n\n\n\n

    First, subtract 32 from 42.5:42.5\u221232=10.542.5 – 32 = 10.542.5\u221232=10.5<\/p>\n\n\n\n

    Now, multiply by 59\\frac{5}{9}95\u200b:Tc=59\u00d710.5=5.8333\u2026\u2009\u00b0CT_c = \\frac{5}{9} \\times 10.5 = 5.8333\\ldots \\, \\text{\u00b0C}Tc\u200b=95\u200b\u00d710.5=5.8333\u2026\u00b0C<\/p>\n\n\n\n

    So, the temperature in Celsius is approximately 5.83\u2009\u00b0C5.83 \\, \\text{\u00b0C}5.83\u00b0C.<\/p>\n\n\n\n

    Step 2: Convert Celsius to Kelvin<\/h3>\n\n\n\n

    Now that we know the temperature in Celsius is approximately 5.83\u2009\u00b0C5.83 \\, \\text{\u00b0C}5.83\u00b0C, we can convert it to Kelvin:TK=5.83+273.15=278.98\u2009KT_K = 5.83 + 273.15 = 278.98 \\, \\text{K}TK\u200b=5.83+273.15=278.98K<\/p>\n\n\n\n

    Thus, the temperature is approximately 279 K<\/strong>.<\/p>\n\n\n\n

    Conclusion<\/h3>\n\n\n\n

    So, the temperature of 42.5\u00b0F corresponds to 279 Kelvin<\/strong>.<\/p>\n\n\n\n
