The temperature of two bodies measured by a thermometer are `t_(1) = 20^(@)C pm 0.5^(@)C` and `t_(2)=50^(@)C pm 0.5^(@)C`. Calculate the temperature difference and the error theirin.

Text Solution

Verified by Experts

`t. = t_(2)-t_(1) = (50^(@)Cpm0.5^(@)C)-(20^(@)Cpm0.5^(@)C)`
`t. = 30^(@)C pm 1^(@)C`
