Question

1. The following formula relates the quantities temperature in Celsius (C) and temperature in kelvins (K).

Answer 1

A) T(K) = T(°C) + 273.15
or
T (°C) = T(K) - 273.15

b) T(K) = 23 + 273.15
    T(K) = 296.15 Kelvin

c) T (°C) = T(K) - 273.15
    T (°C) = 300 - 273.15
    T (°C) = 26.85 °C
So,
300 kelvins > 25 degrees Celsius

Answer 2

(b) If the temperature is 23 in degrees Celsius, what is the temperature in kelvins? Show your work.

C = K − 273.15
23 = K - 273.15
296.15 Kelvin

(c) Which is greater, 300 kelvins or 25 degrees Celsius? Show your work.

To compare, we need to convert both to the same units. We do as follows:

300 Kelvin
25+273.15 = 298.15 K

Therefore, 300 Kelvin is larger.
