Wine Sediment

The kinetic theory of particle … Please help ….?

particle to explain the following: a) When you take a block of butter from the refrigerator, it is very hard. However, after 15 minutes is enough soft to spread. B) the football is to fly until it is hard on a hot summer day. At night, football feels softer.

In addition, one more question: the name of the most suitable method to separate mixtures: a) wine from the sediment formed at the bottom of a bottle of oil spills b) seawater c) of iodine a solid mixture of iodine and salt please please help me with this … you do not have to answer all questions, only one party is well too … PLEASE ….

a) When the bags, is in solid form. When kept at room temperature for a period of time, Hains and absorbing heat energy from the environment and convert into kinetic energy. Therefore, the substance is not hot, is due to the increase in kinetic energy of the particles.

The particles are beginning to vibrate and turn more strongly on their fixed positions and when they acquire enough energy to overcome the powerful forces of attraction between particles, which lose their orderly arrangement, able to move freely glide over others. Then he would have become liquid. Before all the solid particles have become liquid particles, the temperature remains constant since this endothermic reaction is needed to break the attractive forces. The butter is soft to spread its state is between the solid and liquid wherre temperature is rising.

b) On a hot day, gas within football then to expand, and since gas has no fixed volume in a given space, it would try to occupy as much space as possible. Because the forces of attraction between gas particles are negligible, therefore, are more widely spaced to separate solids and liquids. Thus, when pressure is applied, due to the compactness of football, the particles are Foreca be stacked, creating tension.

Therefore, the ball is difficult. But at night, the atmosphere is cool therefore the gas contracts and the kinetic energy of gas particles are slower, therefore not take up much space.

For the last qn, a) the use of decantation, which is the distance of pouring the liquid (wine) and leaving behind sediment since the sediment is more dense than the liquid and sinks.

b) Sorry, for this qn do not know. but to separate the components of oil, using fractional distillation. c) volume as iodine is a simple covalent molecule that has a Low MP and BP, so they are volatile.

This means that at room temperature, iodine is a solid, based on the periodic table, but the particles on the surface of eoungh gains energy to escape as gas particles. Erm, you can try creating an experiment, where heat and salt iodine at 100 degrees celcius (from table salt has a high MP and BP), and put a glass or cooler substance in the mixing vessel so that when the particles sublime iodine gas, which are capable to condense on the cold surface and solid iodine. for salt, evaporated to dryness only as decomposition at 100 degrees celcius dont i hope this helps. I want to answer for you, and can go for my exam for practice a little.
