The sample that has the highest solubility is THE FIRST SAMPLE [TABLE SUGAR NO 1].
Solubility refers to the quantity of a solute that will dissolve in a given volume of solvent at a given temperature and pressure. The question above tells us that equal amounts of sugar and table salts were used. But looking at the table given in the question, you will see that sample 1 has the highest amount of solute that dissolve, that is 80, the rest of the samples have values that are lower than that.
Displacement occurs when an object is immersed in fluid, pushing it out of the way and taking its place. The volume of the object then can be measured by subtracting the fluid without the object from fluid with the object. The amount which the liquid rises in the cylinder is equal to the volume of the object.
Answer:
The order of increasing number of micro states in the resulting system is 3 < 1 < 5 < 2 < 4.
Explanation:
A micro state is a specific way in which we can arrange the energy of the system.Many of then are indistinguishable to each other higher the entropy.
Increase the temperature a volume makes more micro states.
Therefore, the descriptions in order of the increasing number of micro states .
Therefore, the increasing order of micro states in the resulting system is as follows.
3 < 1 < 5 < 2 < 4.
Answer:
H= Planck's Constant
Explanation:
Since light is bundled up into photons, Einstein theorized that when a photon falls on the surface of a metal, the entire photon's energy is transferred to the electron.
The total energy required to convert the unknown liquid to gas at the given temperature is 7.215 kJ.
The given parameters;
- <em>mass of the unknown liquid, m = 19.8 g</em>
- <em>molar mass of liquid = 83.21 g/mol</em>
- <em>initial temperature of the liquid, = 19.2 °C</em>
- <em>boiling point temperature of the liquid, = 57.3°C</em>
- <em>final temperature of the liquid = 93.5 °C</em>
The total heat required to convert the liquid to gas is calculated as follows;
<em>H = Heat to raise to boiling temp. + Heat to vaporize the liquid + Heat of gas vapor</em>
The heat required to raise the temperature of the liquid to boiling point;
The number of moles of the liquid is calculated as;
The heat required to vaporize the liquid;
The heat of the gas vapor is calculated as;
The total energy required to convert the unknown liquid to gas at the given temperature is calculated as;
Thus, the total energy required to convert the unknown liquid to gas at the given temperature is 7.215 kJ.
