Consider a neatly packed box of marbles compared to what you get if you dump the marbles on the floor. Which state has the higher entropy. a. spilled marbles b. marbles in packed box c. none d. both

Answers

Answer 1

Answer:

Answer:

a. spilled marbles

Explanation:

entropy is the tendency toward a state of disorder or randomness, so the spilled box of marbles has the higher entropy

Answer 2

Answer:

Final answer:

The spilled marbles and marbles in a packed box have different states of entropy.

Explanation:

Entropy is a concept in thermodynamics that refers to the disorder or randomness of a system. In this case, the state with the higher entropy would be the spilled marbles. When marbles are neatly packed in a box, they are in a more ordered and organized state, resulting in lower entropy. However, when the marbles are spilled on the floor, they are now in a more disordered and random state, leading to higher entropy. Therefore, the answer is d. both.

Answer : Salinity tolerance

Explanation :

The important characteristics for the plants which are found in salt water wet lands is salinity tolerance.

Salinity tolerance is the salt tolerance of crops in the wet lands which gives maximum salt level that a crop can tolerate without losing its productivity.

Although it may get affected negatively at higher levels of exposure. The salt level is often measured as the soil salinity or else the salinity of the irrigated water.

200 mL of nitrogen gas at 24K is heated to 47K.

Answers

Answer:

See explanation

Explanation:

The question is incomplete. However, base on the given information, one likely question could be that, we calculate the the volume of the nitrogen gas after heating it.

So, we have that:

Initial Volume, V1 = 200mL

Initial Temperature, T1 = 24k

Final Temperature, T2 = 47k

To solve the final volume of the gas, we apply the following ideal gas law equation

V1 * T1 = V2 * T2

Substitute values for V1, T1 and T2

200mL * 24K = V2 * 47K

200mL * 24 = V2 * 47

4800mL = 47V2

Solve for V2

V2 = 4800/47

V2 = 102.13 mL ------- Approximated

Hence, the volume of nitrogen gas after heating is 102.13mL

What interacted directly with the photographic plates to cause images in Becquerel’s experiment?A...uranium salt

B...radiation

C...unstable nuclei

D...radioisotopes

Answers

Answer: A. uranium salt

Becquerel made a conclusion that it was the uranium that causes the images found in the photographic plates. Though his theory was disproved during the first time,he continued to develop it. Then, it is through this experiment that Becquerel discovered radioactivity.

A ________ ion is created when an electron is removed.a. stable
b. neutral
c. positive
d. negative

Answers

Answer: The correct answer is Option c.

Explanation:

Ions are formed when an atom looses or gains electrons.

If an atom gains electrons, it leads to the formation of negative ions known as anions. For Example: Fluorine gains 1 electron to form $F^-$ ions.

If an atom looses electrons, it leads to the formation of positive ions known as cations. For Example: Sodium looses 1 electron to form $Na^+$ ions.
