Question

the reading on a thermometer is -20°C and the temperature rises with 20°C what will the new reading be ​

Answer 1

0°c

Explanation:

-20+20=0 so that is the answer

Answer 2

0°C

Explanation:

If the reading on a thermometer is -20°C and the temperature rises by 20°C, we can find the new reading by adding the change in temperature to the original reading.

Change in temperature = 20°C (given)

New reading = Original reading + Change in temperature

New reading = (-20°C) + 20°C

New reading = 0°C

Therefore, the new reading on the thermometer will be 0°C.
