<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>
Answer:
Number <u>3</u> is the chloroplast. The chloroplast helps the plant obtain food by <u>photosynthesis</u>. Number <u>1</u> is the central vacuole. The central vacuole helps a plant maintain its structure by <u>turgor pressure</u>.
Answer:
D. Cellular respiration releases oxygen and photosynthesis releases carbon dioxide
