Answer:
The first law describes how thermal energy is conserved but not the direction it moves.
Thermodynamics is demonstrated as the branch of physics that deals with the associations or relationships between heat and other energy forms like mechanical, chemical, and electrical).
As per the question, the first law discusses that heat is a kind or form of energy and thus, processes associated with thermodynamics are subject to energy conservation principle. Therefore, heat energy can neither be destroyed nor created but rather transferred to one place to another and converted to and from other energy forms.
Thus, the first law of thermodynamics is distinct from the second law as 'the former describes how thermal energy can be conserved to and from other forms of energy and not the direction in which it moves' while the second law focuses on entropy.

Which of the following processes suggest that matter is made up of minute particles.
Answer:
the answer is evaporation
Explanation: Evaporation is the process by which a liquid transforms into vapor (a gas). When some material is in its liquid phase, its particles are really close together (but not as much as we would see in a metal). As the temperature of the liquid increases, also does the kinetic energy of the particles. This cause the particles in the water to move a lot faster, thus its oscillations are larger. This causes an increase in the volume of the material.
Which of the following would have the largest concentration of chloride ions in solution.
Answer:
From the given options, the solution of 0.10M AlCl₃ is the one that has the highest concentration of chloride ions.
To know which of the given solutions has the highest concentration of chloride ions, we must evaluate each of them.
1) 0.10 M MgCl₂
We can see that in 1 mol of MgCl₂, we have 1 mol of Mg²⁺ and 2 moles of Cl⁻ ions, so if the initial concentration of MgCl₂ is 0.10 M we have:
Hence, in this solution we have 0.20 M of chloride ions.
2) 0.10 M AlCl₃
In 1 mol of AlCl₃, we have 1 mol of Al³⁺ and 3 moles of Cl⁻, so the concentration of Cl⁻ is:
Then, the concentration of chloride ions in this solution is 0.30 M.
3) 0.05 M CaCl₂
We can notice that in 1 mol of CaCl₂ we have 1 mol of Ca²⁺ and 2 moles of Cl⁻. The concentration of Cl⁻ is:
So, the concentration of the Cl⁻ ions is 0.10 M.
4) 0.10 M LiCl
In this case, in 1 mol of LiCl we have 1 mol of Li⁺ and 1 mol of Cl⁻, so the concentration of the chloride ions is:
Hence, in this solution the concentration of the Cl⁻ ions is 0.10 M.
Therefore, the solution 0.10M AlCl₃ has the highest concentration of chloride ions.

A piece of equipment costs $30,000, and is expected to generate $8,500 of annual cash revenues and $1,500 of annual cash expenses. The disposal value at the end of the estimated 10-year life is $3,000. Ignoring income taxes, the payback period is:.
Answer:
C. 4.29 years
Explanation:
The computation of the payback period is shown below:
Payback period = Initial investment of the equipment ÷ Cash flows
where,
Initial investment = $30,000
And, the cash flows is
= $8,500 - $1,500
= $7,000
So the payback period is
= $30,000 ÷ $7,000
= 4.29 years
By dividing the initial investment by the cash flows we can get the payback period and the same is applied above.

A bag contains chips of which 27. 5 percent are blue. A random sample of 5 chips will be selected one at a time and with replacement. What are the mean and standard deviation of the sampling distribution of the sample proportion of blue chips for samples of size 5 ?.
Answer:
No. of blue chips contain in a bag = P = 27.5 % = 0.27
No. of chips random selected at a time with replacement = n = 5
We know that the mean and standard deviation of the sampling distribution of the sample proportion (p) is given by :-
\mu\-_pμ\-p = p
= 0.275
\sigma_pσp = \sqrt{\frac{p (1-p)}{n} }np(1−p)
Where p= Population proportion and n = sample size.
Let p be the proportion of blue chips.
As per given , we have
p= 0.275
n= 5
= \sqrt{\frac{0.275 ( 1 - 0.275)}{5} }50.275(1−0.275)
= 0.1997
The mean and standard deviation of the sampling distribution of the sample proportion will be 1.375 and 0.9984.
What is the mean and standard deviation?The standard deviation is a statistic that expresses how much variance or dispersion there is in a group of numbers. While a high standard deviation suggests that the values are dispersed throughout a larger range, a low standard deviation suggests that the values tend to be near to the established mean.
A bag contains chips of which 27.5 percent are blue. A random sample of 5 chips will be selected one at a time and with replacement.
Then the mean is given as,
Mean = 0.275 x 5
Mean = 1.375
Then the standard deviation is given as,
Standard deviation = √[5 x 0.275 x (1 - 0.275)]
Standard deviation = √0.99687
Standard deviation = 0.9984
The mean and standard deviation of the sampling distribution of the sample proportion will be 1.375 and 0.9984.

The first row shows first truck and has, startfraction 1 over 5 endfraction, t, and startfraction 1 over 5 endfraction times t. The second row shows second truck and has, startfraction 1 over 8 endfraction, t, and startfraction 1 over 8 endfraction times t. When the two crews start working together, what part of all the garbage bins will the first garbage truck empty? 0. 6 0. 5 0. 7 0. 4.
When the two crews start working together, the part of all the garbage bins that the first garbage truck will empty is; A: 0.6
We are told that the first truck empties all bins in 5 hours. Thus;
Rate of first truck per hour = ¹/₅
Second truck empties all bins in 8 hours. Thus;
Rate of second truck per hour = ¹/₈
If both trucks work together, their rate per hour is;
Combined rate per hour = ¹/₅ + ¹/₈
Combined rate per hour = ¹³/₄₀
Thus, number of hours it will take for both of them to do the whole job, we will solve as;
¹³/₄₀t = 1
where t is the time it will take both of them combined to finish the whole job.

The cost of mailing a first-class letter is $0. 46.
Answer:
Explanation:
If y is the total cost to mail a letter, that is what your equation should be set equal to.
y = _________
Then, just to be able to send the letter, you have to pay .46 before you even weigh it.
y = 0.46 + _____
Finally, you can weigh your letter to determine how much more you'd have to pay (it wouldn't be fair if a 1 ounce letter and a 5 pound letter costed the same!). The problem gives you the variable for ounces, so you would do
price x ounces.
y = 0.46 + 0.20x
