Conversion factor involves same units. For example, length can be converted to length only, time to time only, etc.
Name and unit are listed, which is NOT correctly written?
-
Torr and pressure
-
Mass and grams
-
Heat energy and kilopascals
-
Volume and milliliter
-

Unit of Heat energy is joule ($J$) not kilopascals. kilopascal is unit for pressure.
Convert $48.50mL$ to liters.
-
$0.4850L$
-
$4850L$
-
$0.04850L$
-
$0.00004850L$
-
$4.850L$
We know that the 1 mL is equals to 0.001 L
Unit of J $pa^{-1}$ is equivalent to:
-
$m^3$
-
$cm^3$
-
$dm^3$
-
none of these
J/Pa = Work/Pressure = Nm/Nm-2 = m3
298 K is approximately what temperature in degrees Celsius?
-
$25^oC$
-
$24^oC$
-
$29^oC$
-
$27^oC$
Zero on the Celsius scale $(0^0C)$ is now defined as the equivalent to $273.15K$, with a temperature difference of $1^0C$ equivalent to a difference of $1K$, meaning the unit size in each scale is the same.
