Answer:
C.Supersaturated
Explanation:
There are three types of solution:
<u>SATURATED SOLUTION</u>:
It is the solution that contains maximum amount of solute dissolved in a solution in normal conditions.
<u>UNSATURATED SOLUTION</u>:
It is the solution that contains less than the maximum amount of solute dissolved in a solution in normal conditions. It has space for more solute to be dissolved in it.
<u>SUPERSATURATED SOLUTION:</u>
It contains more than the maximum amount of solute dissolved in it. Such a solution has no capacity to dissolve any more solute under any conditions.
Since the sugar is no more dissolving in the tea and has settled down. Therefore, the solution is:
<u>C.Supersaturated</u>
Answer:
Explanation:
When the cold milk is added into the hot coffee, heat is transferred from the coffee (higher temperature) to the milk (lower temperature), until the two substances are at the same temperature (thermal equilibrium).
Therefore, the heat given off by the coffee is equal to the heat absorbed by the milk; so, we can write:
where:
is the mass of coffee
is the specific heat capacity of coffee
is the initial temperature of the coffee
is the mass of milk
is the specific heat capacity of milk
is the initial temperature of milk
is the temperature at equilibrium
Solving for , we find the final temperature of the coffee at equilibrium:
