Question

Which one is greater among 40°C, 40°F and 40K?​

Answer 1

To compare these temperatures, we need to convert them to the same unit of temperature.

To convert Celsius (°C) to Kelvin (K), we add 273.15 to the Celsius value.

40°C + 273.15 = 313.15 K

To convert Fahrenheit (°F) to Celsius (°C), we can use the formula:

°C = (°F - 32) * 5/9

So,

40°F = (40 - 32) * 5/9 = 4.44°C

Now, we can convert 4.44°C to Kelvin using the formula:

4.44°C + 273.15 = 277.59 K

So the order from smallest to largest temperature is:

40°F < 4.44°C < 40°C < 277.59 K

Therefore, 40K is the greatest temperature among the three.
