A "FORCE" is required to cause acceleration or cause an object to move.
Answer:
Boiling Point and Melting point = Condensation Point and Freezing Point
Explanation:
Such is easily seen on the 'Heating Curve for Water' (see attached). Note the regions that have zero slope. Trace back to y-axis of graph. These points are the phase transition temperatures for freezing (Iiquid => solid)/melting of ice (solid => liquid) and boiling of water (liquid => gas) / condensation (gas => liquid).
Note also, during phase change (heating or cooling), two phases will always be present (solid & liquid) or (liquid & gas) and experience 0 temperature change during the transitions (zero slope regions). The regions having slope values are heating or cooling of pure single phase form of the substance and do not represent phase change in those regions.
Answer:
%age Yield = 87.16 %
Explanation:
Percentage yield is the ratio of actual yield to theoretical yield. The actual yield the amount of product obtained after the experiment and the theoretical yield is the amount of ideal product obtained on paper calculations. The actual yield is almost always less than the theoretical yield due to chemical reaction problems, or handling problems.
Given Data:
Theoretical Yield = 25.31 g
Actual Yield = 22.06 g
%age Yield = ?
Formula Used:
%age Yield = (Actual Yield ÷ Theoretical Yield) × 100
Putting Values,
%age Yield = (22.06 g ÷ 25.31 g) × 100
%age Yield = 87.16 %
