QUESTION:
When adding or subtracting measured quantities, what determines the number of significant figures in the result?
ANSWER:Solution 28E: (a) The temperature on a warm summer day is 87 °F We know, The relation between celsius scale and Fahrenheit scale oC= 5/9( F-32) or F=9/5( C)+32 o = 5/9(87-32) = 5/9(55) o = 30.55 C o Thus the temperature in °C is 30.55 C (b) 25 °C The relation between celsius scale and Kelvin scale is given below We know, o K= C + 273.13 = 25 + 273.13 =298.13 K Thus the temperature in Kelvin scale is 298.13 K We know The relation between celsius scale and Fahrenheit scale is
