The temperature of an object is raised by 90ºC. This is equivalent to what increase in its absolute temperature?

To find the increase in absolute temperature, we need to understand the relationship between temperature in degrees Celsius (ºC) and temperature in Kelvin (K). The Kelvin scale is an absolute temperature scale, with 0 K representing absolute zero (the lowest possible temperature).

The conversion from degrees Celsius to Kelvin is done by adding 273.15 to the temperature in ºC. This is because the Kelvin scale starts at absolute zero, which is equivalent to -273.15 ºC.

So, to find the increase in absolute temperature, we need to convert the increase in degrees Celsius to Kelvin.

Given that the temperature is raised by 90ºC, we can calculate the increase in absolute temperature as follows:

Increase in absolute temperature = Increase in degrees Celsius + 273.15

Increase in absolute temperature = 90ºC + 273.15

Increase in absolute temperature ≈ 363.15 K

Therefore, the increase in absolute temperature is approximately 363.15 K.
