The two.
When using significant digits, the product has only the number of significant digits as the lowest number in the factors. "20" has two significant digits and "310" has three. Therefore, the product has to have two significant digits. 310 × 20 = 6200 6200 already has two significant digits.
20 degree Celsius = 68 degree Fahrenheit
-20 degree Celsius = -4 degree Fahrenheit.Conversion to Fahrenheit: -4°F
Two. The decimal indicates that the zero is significant otherwise it wouldn't be a significant digit.
Potassium has a gram atomic mass of 39.1, to three significant digits (one more significant digit than "20 meq" has). Therefore, one meq = 39.1 mg, and 20 meq = 20(39.1) = 7.8 X 102 mg, to the justified number of significant digits.
20 degree Celsius = 68 degree Fahrenheit

18 degrees Celsius is colder than 20 degrees Celsius.
-20 degree Celsius = -4 degree Fahrenheit
The answer is -20º celsius is colder than -18º celsius.
Significant digits refer to the number of digits that are known versus the number of digits that are estimated. So if the number 20 is an approximation, there is only one significant digit, which is the 2. However, if 20 is accurate to the ones place, then there are 2 significant digits. 20.00 has four significant digits, because it is known that the number is accurate down to the hundredths place.
Gold is a solid at 20 degrees Celsius.
100C - 20C equals 80C
20 degree Celsius = 68 degree Fahrenheit
20 degrees Celsius = 68 degrees Fahrenheit.
40 degrees Fahrenheit, as 20 degrees Celsius equals 68 degrees Fahrenheit
