Explanation:
Answer:
The unknown solution had the higher concentration.
Explanation:
When two solutions are separated by a semi-permeable membrane, depending on the concentration gradient between the two solutions, there is a tendency for water molecules to move across the semi-permeable in order to establish an equilibrium concentration between the two solutions. This movement of water molecules across a semi-permeable membrane in response to a concentration gradient is known as osmosis. In osmosis, water molecules moves from a region of lower solute concentration or higher water molecules concentration to a region of higher solute concentration or lower water molecules concentration until equilibrium concentration is attained.
Based on the observation that when the glucose solution described in part A is connected to an unknown solution via a semipermeable membrane, the unknown solution level rises, it means that water molecules have passed from the glucose solution through the semipermeable membrane into the unknown solution. Therefore, the solution has a higher solute concentration than the glucose solution.
Answer:
Explanation:
As we know that,
.................(1)
where,
q = heat absorbed or released
= mass of metal = 100.0 g
= mass of water = 100.0 g
= final temperature =
= temperature of metal =
= temperature of water =
= specific heat of metal = ?
= specific heat of water=
Now put all the given values in equation (1), we get
Therefore, the specific heat capacity of metal is
