1.	The temperatures of two bodies measured by a thermometer are t_(1) = (20 pm 0.5)^(@)C, t_(2) = (50 pm 0.5)^(@)C. Calculate the temperature difference and the error therein.
Answer» SOLUTION :`t_(1) = (20 pm 0.5)^(@)C t_(2) = (50 pm 0.5)^(@)C` TEMPERATURE DIFFERENCE t = ? t = `t_(2) - t_(1) = (50 pm 0.5) - (20 pm 0.5)^(@)C` `= (50-20)pm(0.5+0.5)` t = `(30pm1)^(@)C`
