<span>D. A burning candle. (chemical energy into energy of heat and light, i.e. thermal and wave)</span>
vladimir1956 [14]3 years ago
4 0

Answer: Option (D) is the correct answer.

Explanation:

When we burn a candle then combustion reaction takes place as it results in the formation of carbon dioxide gas and water in the form of vapors (stream).

Thus, we can conclude that when a candle is burnt then chemical energy gets converted to heat energy or light energy.

As due to this heat energy the wax starts to melt.

The entropy of an isolated system must be conserved, so it never changes.a. Trueb. Fasle
Snowcat [4.5K]

Answer:

B: False

Explanation:

The second law of thermodynamics states that: the entropy of an isolated system will never decrease because isolated systems always tend to evolve towards thermodynamic equilibrium which is a state with maximum entropy.

Thus, it means that the entropy change will always be positive.

Therefore, the given statement in the question is false.

I need help with these questions.
strojnjashka [21]

I'll go ahead and answer the ones here without an answer. For reference, the half-life formula is <em>final amount = original amount(1/2)^(time/half-life)</em>

<em />

4) 12.5g

x = 100(1/2)^(63/21)

5) 50g

3.125 = x(1/2)^(0.1/0.025)

6) 500g

x = 4000(1/2)^(525/175)

7) 0.24g

0.06 = x(1/2)^(11430/5730)

8) 125g

x = 1000(1/2)^(17100/5700)

Hope this helps! :)
