Salsk061 [2.6K]

Answer:

Part A:

"360 grams of NaCl can be dissolved in 1 L water. So, 2000 grams sugar can be dissolved in 1 L water then we can say that the solubility of salt is lesser in water as to sugar and both heightened by increasing the temperature. If we make a batch of 800 L we can add sugar, 1600 kg at 25 0c. We can add salt is 288 kg at 25 0c and the ingredient tomato is having low solubility."

Which of the following processes have a ΔS < 0? Which of the following processes have a ΔS < 0? carbon dioxide(g) → carbon
Umnica [9.8K]

Answer:

All of the above processes have a ΔS < 0.

Explanation:

ΔS represents change in entropy of a system. Entropy refers to the degree of disorderliness of a system.

The question requests us to identify the process that has a negative change of entropy.

carbon dioxide(g) → carbon dioxide(s)

There is  a change in state from gas to solid. Solid particles are more ordered than gas particles so this is a negative change in entropy.

water freezes

There is  a change in state from liquid to solid. Solid particles are more ordered than liquid particles so this is a negative change in entropy.

propanol (g, at 555 K) → propanol (g, at 400 K)

Temperature is directly proportional to entropy, this means higher temperature leads t higher entropy.

This reaction highlights a drop in temperature which means a negative change in entropy.

methyl alcohol condenses

Condensation is the change in state from gas to liquid. Liquid particles are more ordered than gas particles so this is a negative change in entropy.

The energy pyramid below shows a possible
ExtremeBDS [4]

Energy transfer is not an efficient process.

Explanation:

There is less amount of energy in the top of the energy pyramid than at the bottom because energy transfer is not an efficient process. During the process of energy transferring, some amount is lost and some are converted to other forms of energy.

  • The sun is the ultimate source of energy for all life in the solar system.
  • When autotrophs takes this energy, they produce food from it.
  • They use light energy from the sun to produce chemical energy in food.
  • Even this conversion process waste precious amount of energy.
  • As one goes up the pyramid, more energy is lost during the process of converting from one form to another.
