Question

ADVANCED MATERIAL Predicting qualitatively how entropy changes with temperature and volume Jace For each system listed in the first column of the table below, decide (if possible) whether the change described in the second column will increase the entropy S of the system, decrease S, or leave Sunchanged. If you don't have enough information to decide, check the "not enough information" button in the last column. System Change AS O A80 AXO A few grams of liquid acetone (CHCO). The acetone is cooled from 9.0 4. 00 C to A > 0 not enough information AS < 0 ASO A few moles of carbon dioxide (CO) gas. The carbon dioxide expands from a volume of 1.0 L to a volume of 7.0 L while the temperature is held constant at 50.0 °C. not enough information ASCO AS=0 A few moles of nitrogen (N) gas. The nitrogen is heated from -5.0°C to 90.0 °C and is also compressed from a volume of 9.0 L to a volume of 8.0L AS > 0 not enough Explanation ) Check

Answer 1

When gas is heated moles of gas is increased and cooled moles of gas dicreased becouse randomness of systems in changes

When Volume of gas increase randomness of gases molecule increase due to more space of same quantity molecule.

If randomness increase S also increase vice versa

Delta S and S both are different, concept- temprature increase any system S always increase but delta S= Wreversible /T Temperature increase delta S decrease

Volume increase delta S always increase.
