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.

The temperature of two bodies measured by a thermometer are t_(1) = 20

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