Answer:

The mass of the bar is approximately 0.33 g.

Explanation:

q (heat in joules) = 1000 J

c (specific heat capacity) = 52 J/g°C

ΔT (change in temperature) = 80 - 22 = 58°C.

m (mass in grams) = ?

m = q / cΔT

m = 1000 J / (52 J/g°C) (58°C)

m = 0.33 g

hope this helps and is right!! p.s. i really need brainliest :)

Unlike most chemical changes, most physical changes are easily reversed. When Adrian's teacher dissolves some sugar in a beaker

pochemuha

Answer:

By heating the solution

Explanation:

Physical changes and chemical changes are the two types of changes that a substance undergoes. Physical change does not alter the substance's chemical composition, hence, can be easily reversed. There is also no new product formed. This is contrary to the occurrences of a chemical change, which cannot be reversed after a new product has been formed.

A physical change is what occurs when Adrian's teacher dissolves some sugar in a beaker of water to form a sugar solution. This change does not involve any new product formation, hence, can be reversed. The sugar can be derived back from the solution by HEATING THE SOLUTION. The water (solvent) will evaporate and the sugar (solute) will precipitate.
