In a fixed volume when temperature increases , pressure does what?
Leni [432]

<u>Answer:</u>

<em>When the volume is constant the pressure increases with temperature.  </em>

<u>Explanation:</u>

<em>Gay Lussac’s law precisely explains the relation between pressure and temperature of a system which has constant volume.</em> In a system which has constant volume an increase in temperature indicates increase in temperature as well.

The reason behind the observation of this trend is the change in <em>randomness of particles of the system.  </em>

With increase in temperature the particle movement becomes random and fast. <em>The particles hit the container walls at an increased rate and the pressure of the system increase.  </em>

babymother [125]

Answer:

The use of flashback in "Rules of the Game" provides insight into the complicated relationship between Waverly and her mother.

Waverly sees events differently because of her American upbringing. Her mother sees events differently because of her Chinese upbringing. Waverly notes that her mother has had difficulty adjusting to American culture. She shows this struggle when she describes her mother’s reaction to the game manual for her brother’s new chess set:

“This American rules,” she concluded at last. “Every time people come out from foreign country, must know rules. You not know, judge say, Too bad, go back. They not telling you why so you can use their way go forward. They say, Don’t know why, you find out yourself. But they knowing all the time. Better you take it, find out why yourself.” She tossed her head back with a satisfied smile.
