Question 2785
Which test is performed to detect coliform bacteria in milk as an indicator of post-pasteurization contamination?
Correct Answer Logic:
Coliform bacteria (\(E.\;coli\), \(Klebsiella\), \(Enterobacter\)) should be absent or very low in properly pasteurized milk. Detection uses the MPN method (lauryl sulfate tryptose broth with gas production) or direct plating on selective media (VRBA, Petrifilm CC). Coliforms in pasteurized milk indicate post-pasteurization contamination.

Question 2786
Pre-emergence herbicides are most effective when:
Correct Answer Logic:
Pre-emergence herbicides act on germinating seeds in the soil โ they must be incorporated into the top 2โ5 cm of the germination zone by rainfall or irrigation (activation) to contact the target weed. They form a chemical barrier disrupting cell division or pigment synthesis in germinating seedlings. Dry, crusted soil surfaces, delayed activation, and deep-plowed weed seeds reduce their efficacy.

Question 2787
In the analysis of indeterminate structures using the Flexibility (Force) Method, the compatibility equation for a structure with \(n\) redundants is expressed in matrix form as:
Correct Answer Logic:
The compatibility equation in the Force Method is \([F]\{X\} + \{D_0\} = \{0\}\) (or equivalently \([F]\{X\} = -\{D_0\}\)), where \([F]\) is the flexibility matrix (flexibility coefficients \(f_{ij}\) = displacement at \(i\) due to unit force at \(j\)), \(\{X\}\) is the vector of redundants, and \(\{D_0\}\) is the displacement vector of the released structure (primary structure) under applied loads. Option B is the stiffness method equation.

QUESTION #7509
Question 2791
The volume occupied by 4.75 g of acetylene gas (C$_2$H$_2$) at 50ยฐC and 740 mmHg pressure is approximately _____ L.
$[R = 0.0826\ \text{L atm K}^{-1}\ \text{mol}^{-1}]$
Correct Answer Logic:
Molar mass of C$_2$H$_2 = 2(12) + 2(1) = 26\ \text{g/mol}$
Moles $= \dfrac{4.75}{26} \approx 0.1827\ \text{mol}$
$T = 50 + 273 = 323\ \text{K}$
$P = \dfrac{740}{760}\ \text{atm} \approx 0.9737\ \text{atm}$
$V = \dfrac{nRT}{P} = \dfrac{0.1827 \times 0.0826 \times 323}{0.9737} \approx \dfrac{4.875}{0.9737} \approx \mathbf{6}\ \text{L}$

QUESTION #3824
Question 2793
If $400$ mg of potassium permanganate is dissolved in $2.5$ L of water, what is the percentage concentration of the resulting solution?
Correct Answer Logic:
$400\ \text{mg} = 0.4\ \text{g}$ in $2500\ \text{mL}$. Concentration $= \dfrac{0.4}{2500} \times 100 = 0.016\%\ \text{w/v}$.

QUESTION #7139
Question 2794
Which of the following crystal defects occurs when an ion is displaced from its regular lattice site to an interstitial position?
Correct Answer Logic:
The Frenkel defect is a dislocation defect where an ion (usually the smaller cation) leaves its original lattice site and occupies an interstitial space. This creates a vacancy at the original site but does not change the overall density of the crystal.

QUESTION #9626
Question 2800
Gross Profit is Rs. 40,000. Administrative expenses are Rs. 15,000, selling expenses Rs. 5,000, and financial expenses Rs. 5,000. There is also other income of Rs. 2,000. What is the Net Profit?
Correct Answer Logic:
Net Profit = Gross Profit โ Operating Expenses + Other Income. Operating expenses = 15,000 + 5,000 + 5,000 = Rs. 25,000. Operating Profit = 40,000 โ 25,000 = Rs. 15,000. Add other income: 15,000 + 2,000 = Rs. 17,000.
