11 / 20

Which of these statements about temperature units are correct or incorrect?

1. 20° Celsius = 68° Fahrenheit.
2. 0° Celsius = 273° Kelvin.

  • A
    1 is correct, 2 is correct.
  • B
    1 is correct, 2 is incorrect.
  • C
    1 is incorrect, 2 is correct.
  • D
    1 is incorrect, 2 is incorrect.

Conversion of temperature between Celsius, Fahrenheit, and Kelvin may be achieved using the following formulas:

°C = °K - 273

°F = 1.8 x °C + 32

Therefore:

  1. °F = 1.8 x °C + 32 => 1.8 x 20 +32 = 68°F
  2. °C = °K - 273 => 273 – 273 = 0°C
Both statements are correct.
