<span>Colligative properties are properties of solutions that depend on the number of molecules [or ions] in a given volume of solvent and not on the properties (e.g. size or mass) of the compound. Colligative properties include: lowering of vapor pressure; elevation of boiling point; depression of freezing point and osmotic pressure.</span>
Answer: The author used the word "conversely" because the first statement he made is in CONTRAST to the second statement he made.
Explanation:
Matter is made up of atoms or molecules that are in constant motion. The motion of these tiny particles ( molecules) gives the object energy. The movement of these molecules depends on the state of matter which includes
--> GASEOUS STATE: Here, the particles are completely free to move and are always in motion.
--> LIQUID STATE: particles in this state slide by one another and are always in motion.
--> SOLID STATE: particles in this state are held tightly together but are always in motion.
Also, the molecules in motion are greatly affected by temperature changes. Increase in temperature will cause the particles in the liquid to move faster. Such is seen when soup is heated, the molecules travel faster than before. But the OPPOSITE is seen in an ice cube. This is because the ice cube is in solid state and of a lower temperature.
Answer:
The new temperature of the water bath 32.0°C.
Explanation:
Mass of water in water bath ,m= 8.10 kg = 8100 g ( 1kg = 1000g)
Initial temperature of the water = ![T_1=33.9^oC=33.9+273K=306.9 K](https://tex.z-dn.net/?f=T_1%3D33.9%5EoC%3D33.9%2B273K%3D306.9%20K)
Final temperature of the water = ![T_2](https://tex.z-dn.net/?f=T_2)
Specific heat capacity of water under these conditions = c = 4.18 J/gK
Amount of energy lost by water = -Q = -69.0 kJ = -69.0 × 1000 J
( 1kJ=1000 J)
![Q=m\times c\times \Delta T=m\times c\times (T_2-T_1)](https://tex.z-dn.net/?f=Q%3Dm%5Ctimes%20c%5Ctimes%20%5CDelta%20T%3Dm%5Ctimes%20c%5Ctimes%20%28T_2-T_1%29)
![-69.0\times 1000 J=8100 g\times 4.18 J/g K\times (T_2-306.9 K)](https://tex.z-dn.net/?f=-69.0%5Ctimes%201000%20J%3D8100%20g%5Ctimes%204.18%20J%2Fg%20K%5Ctimes%20%28T_2-306.9%20K%29)
![-69,000.0 J=8100 g\times 4.18 J/g K\times (T_2-306.9 K)](https://tex.z-dn.net/?f=-69%2C000.0%20J%3D8100%20g%5Ctimes%204.18%20J%2Fg%20K%5Ctimes%20%28T_2-306.9%20K%29)
![T_2=304.86 K=304.86 -273^oC=31.86^oC\approx 32.0^oC](https://tex.z-dn.net/?f=T_2%3D304.86%20K%3D304.86%20-273%5EoC%3D31.86%5EoC%5Capprox%2032.0%5EoC)
The new temperature of the water bath 32.0°C.
I don’t! Know bit I guess it’s C
