Question

The temperature at a place rises from -20°C to 20° C.What is the rise in temperature? solution​

Answer 1

Answer:

The rise in temperature at

The rise in temperature at the place is {20-(-20)}°C

The rise in temperature at the place is {20-(-20)}°C= 20 +20 = 40°C.

Step-by-step explanation:

1. As given, the initial temperature at that place is -20°C and the final temperature is 20°C.
2. First, the temperature will rise from -20°C to 0°C which means that the temperature rise is 20°C.
3. Again, the temperature will rise from 0°C to 20°C which also suggests that the temperature rise is 20°C.
4. So, Total temperature rise from -20°C to 20 °C is (20+20)°C = 40°C.
