QUESTION:
When multiplying or dividing measured quantities, what determines the number of significant figures in the result?
ANSWER:Solution 27 E: The temperature scale can be kelvin (K), centigrade ( C) and Fahrenheit ( F). o K= C + 273.13 , C= 5/9( F-32) or F=9/5( C)+32 o (a) 72 °F to °C Conversion of temperature from °F to °C We know, oC= 5/9( F-32) =5/9(72-32) = 5/9 x 40 =22.22 C o Thus the temperature in Celsius is 22.22 C (b) 216.7 °C to °F, Conversion of temperature from °C to °F We know, o C= 5/9( F-32) or F=9/5( C)+32 = 9/5(216.7)+32 = (390.06+32) °F = 422.06 °F Thus the temperature in Fahrenheit ( F). is 422.06 °F c) 233 °
