Answer:
The entropy of a substance can be obtained by measuring the heat required to raise the temperature a given amount, using a reversible process . The standard molar entropy, So, is the entropy of 1 mole of a substance in its standard state, at 1 atm of pressure. (Below are listed tips)
- At absolute zero (0 K), the entropy of a pure, perfect crystal is zero.
- The entropy of a substance can be obtained by measuring the heat required to raise the temperature a given amount, using a reversible process.
- The standard molar entropy, So, is the entropy of 1 mole of a substance in its standard state, at 1 atm of pressure.

Answer:
D
Explanation:
D states a problem because of the population growing. Regulate means control and d stated that their was a problem and a need to control it. Therefore, d I'd really the only valid answer.
Pure Aluminum is too expensive
Answer:
It converts energy in food into a more usable form. (Cellular Respiration-The enzyme-controlled process in which energy is released from food and converted into a form that the cell can use.)
Explanation:
Data:
V1 (initial volume) = 233 mL
P1 (initial pressure) = 622 kPa
V2 (final volume) = ? (mL)
P2 (final pressure) = 988 kPa
Formula:
P1 * V1 = P2 * V2
Solving:
P1 * V1 = P2 * V2
622 * 233 = 988 * V2
114926 = 988 V2
988 V2 = 114926
