Question

Perform the following temperature conversions; round your answers to the nearest whole number.

a) 37°C to kelvins
b) 25°C to degrees Fahrenheit
c) -5°F to kelvins

Answer 1

To convert temperatures, one can use conversion formulas: for Celsius to Kelvin add 273.15, for Celsius to Fahrenheit apply (C × 9/5) + 32, and for Fahrenheit to Kelvin convert to Celsius first then add 273.15. The converted temperatures are 310 K, 77°F, and 253 K.

Step-by-step explanation:

To perform the temperature conversions and round the answers to the nearest whole number, we can use the equations for converting between Celsius, Kelvin, and Fahrenheit.

Conversions

1. 37°C to kelvins: To convert degrees Celsius to kelvins, add 273.15 to the Celsius temperature. Therefore, 37°C + 273.15 = 310.15 K, which rounds to 310 K.
2. 25°C to degrees Fahrenheit: To convert degrees Celsius to Fahrenheit, apply the formula (C × 9/5) + 32. So for 25°C, it's (25 × 9/5) + 32 = 77°F, rounding to 77°F.
3. -5°F to kelvins: First, convert Fahrenheit to Celsius using the equation (F - 32) × 5/9, then add 273.15 to convert to kelvin. For -5°F: (-5 - 32) × 5/9 = -20.56°C, then -20.56°C + 273.15 = 252.59 K, which rounds to 253 K.

These temperature conversions are common in the study of thermodynamics and the properties of matter.
