Each of the identical volumetric flasks contains the same solution at two different temperatures. There are two identical volume
tric flasks. The first volumetric flask is at 25 degrees Celsius and is filled with a solution to approximately 50% of the neck of the flask. The second volumetric flask is at 55 degrees Celsius and is filled with a solution to approximately 80% of the neck of the flask. What changes for the solution with temperature?
We know that molarity is the number of moles of solute present in liter of solution.
Mathematically, Molarity =
As molarity is dependent on volume and volume of a solution or substance is dependent on temperature. So, with increase in temperature there will occur a decrease in volume of the solution. As a result, molarity will increase as it is inversely proportional to volume.
Hence, molarity of both the solutions will be different as temperature of both the solutions is different.
The water phase with the smallest temperature increase when adding 10 kcal of heat is solid ice.
Explanation:
The rest of the statements are incorrect. The density of ice is lower than the density of water. The heat capacity of solid ice is greater almost twice the heat capacity of the liquid water. The heat capacity of vapors is less than heat capacity of liquid.
