Question

On a day when the temperature reaches 53 degree F, what is the temperature in degrees Celsius and in kelvins? Conceptualize In the United States, a temperature of 53 degree F is well understood. In many other parts of the world, however, this temperature might be meaningless because people are familiar with the Celsius temperature scale. Categorize This example is a simple substitution problem. Solve T_F = 9/5 T_C + 32 degree F for the Celsius temperature and substitute numerical values: T_C = 5/9 (T_F - 32) = 5/9 (53 - 32) = 11.66 degree C Use T_C = T - 273.15 to find the Kelvin temperature: T = T_C + 273.15 = 284.82 K A convenient set of weather-related temperature equivalents to keep in mind is that 0 degree C is (literally) freezing at 32 degree F, 10 degree C is cool at 50 degree F, 20 degree C is room temperature, 30 degree C is warm at 86 degree F, and 40 degree C is a hot day at 104 degree F. A substance has a melting point of 1, 243 degree C and a boiling point of 2, 640 degree C. (a) Express these temperatures in kelvins. melting point = K boiling point = K (b) Express these temperatures in degrees Fahrenheit. melting point = degree F boiling point = degree F

Explanation / Answer

From the given question,

TF=(9/5)TC+32

T=TC+273.15

Melting point of substance=12430C=Tc

Melting poin in kelvin=1243 + 273.15=1516.15K

Boiling point of substance=26400C=Tc

Boiling poin in kelvin=2640 + 273.15=2913.15K

TF=(9/5)TC+32

Melting point in degree fahrenheit

TF=(9/5)(1243)+32

=2269.40F

Boiling point in degree fahrenheit

TF=(9/5)(2640)+32

=47840F
