Answer is: D.a heterogeneous mixture and a suspension.
Suspension is a heterogeneous mixture (solute particles do not dissolve), that contains solid particles (for example nickel sulfide or NiS) sufficiently large for sedimentation.
The internal phase (solid nickel sulfide) is dispersed throughout the external phase (water).
Another example of a suspension is sand in water.
Answer:
The amount of sugar that can dissolve in water increase .
Explanation:
Answer: 5 grams of liquid water at 20°C will have more energy.
Explanation:
Kinetic energy is the measure of temperature of the system.
The equation used to calculate kinetic energy of a particle follows:
where,
E = kinetic energy of the particles
k = Boltzmann constant =
T = temperature of the particle
From the above relation, it is visible that kinetic energy is directly related to the temperature of the system.
If the temperature of the particles is high, it means that the particles will have more energy.
We are given:
5 grams of ice cubes at -10°C
5 grams of liquid water at 20°C
So, the temperature of water particles is more than the temperature of ice cube.
Hence, 5 grams of liquid water at 20°C will have more energy.
Temperature dependency is responsible for the process that hot water freeze faster than cold water.
The effect given above is called Mpemba Effect. According to this idea hot water freezes more quickly as compared to cold water. But until now there is no convincing explanation for this strange phenomenon. One idea is that hot containers make better thermal contact with a refrigerator and so conduct heat more efficiently because a good conductor is good fro the transfer of heat. Another idea about this effect is that warm water evaporates more quickly and since this is an endothermic process, it cools the water making it freeze more quickly.
warm water evaporates rapidly and since this is an endothermic process, it cools the water making it freeze more quickly.
