The initial and final temperatures of liquid in a container are observed to be `7.63 +- 0.4^(@) C and 67.7 +- 0.3 ^(@) C`. Determine the fall in the temperature of the liquid.

Text Solution

Verified by Experts

The correct Answer is:
`8.6 +- 0.7^(@) C`
Fall in temperature ` = ( 76.3 +- 0.4 ^(@) C) - ( 67.7 +- 0.3^(@) C)`
` = 8.6 +- 0.7^(@) C`
