In the world’s coldest freezer, sodium gas was cooled to a temperature of 78.5°c below zero and then cooled 194.65°c more. what was the new temperature of the sodium gas?
–273.15°c

–272.7°c

–202.5°c

–116.15°c

A.

Step-by-step explanation:

We are given that

Sodium gas cooled to a temperature =-78.5 degree Celsius

It takes negative because we are given that temperature below zero

Further sodium gas cooled to a temperature =-194.65 degree Celsius

We have to find the new temperature of the sodium gas.

To find the new temperature of sodium gas we will add the given both temperature values

Now, adding two given values then, we get

The new temperature of sodium gas=

Hence, the new temperature of sodium gas=

Option A is true.
