Answer:
C) The mass will double.
Explanation:
The amount of solute that will dissolve will also double since the solvent volume has doubled.
There is a fine liner relationship between amount of solute and solvent that can form a solution.
- A solute is the substance that is dissolved in another.
- A solvent is the medium by which a solute is dissolved.
- A combination of solute and solvent forms a mixture called solution.
To form a solution, solvation must take place. During solvation, the molecules of the solvent surrounds the solute completely and bring them into the phase of dissolution.
Generally, the more the solvent, the more the solute it is able to dissolve.
A table spoon of sugar for example will dissolve readily in a jar of water without settling. In a bucket, it is even much more easier.
1. Heat always flow from a region of higher temperature
to a lower temperature, just like concentration gradient. So in this case,
since the metallic sphere is hotter than water, so naturally heat energy flows
from the metallic sphere to the water.
2. We use the formula:
Q = m C ∆T
where Q is the heat energy gained, m is mass of water, C
is heat capacity of water = 4.184 J/g°C and ΔT is change in temperature
Since density of water is 1 g/mL, so mass is also 100g,
therefore:
Q = 100 g * 4.184 J/g°C * (27.1°C - 25°C)
Q = 878.64 J
3. Heat gained by the water is equal to the heat lost by
the metal, therefore:
Q(water) = - Q(metal)
878.64 J = - 15 g * C * (27.1°C - 98°C)
C = 0.83 J/g°C
