Q2. The density of a certain oil on frying becomes 0.4 kgm⁻³ with the volume of 20m³. What will be its initial volume when its initial density is 0.8 kgm⁻³ assuming no loss of oil due to spillage?
A12 m³
B10 m³
C8 m³
D5 m³
Correct Answer: B
Given information:
Initial density (ρ₁) = 0.8 kg/m³
Final density (ρ₂) = 0.4 kg/m³
Final volume (V₂) = 20 m³
Initial volume (V₁) = ?
No loss of oil (mass conserved)
Key principle:
Mass remains constant (no spillage)
m₁ = m₂
Using density formula:
m = ρV
Step 1: Set up equation
ρ₁V₁ = ρ₂V₂
Step 2: Solve for initial volume
V₁ = (ρ₂V₂)/ρ₁
Substituting values:
V₁ = (0.4 × 20)/0.8
V₁ = 8/0.8
V₁ = 10 m³

Q3. Two cylinders A and B contain 50 cm³ of oxygen and nitrogen, respectively, at the same temperature and pressure. If cylinder A has 5.0 moles of oxygen, how many moles of nitrogen are in cylinder B?
A5.0
B4.0
C3.5
D2.5
Correct Answer: A
Avogadro’s law states that equal volumes of gases at the same temperature and pressure contain the same number of moles. Thus, 50 cm³ of nitrogen in B has the same 5.0 moles as oxygen in A.

Q4. To what temperature must a gas at 273 K be heated to double both its volume and pressure?
A298 K
B546 K
C819 K
D1092 K
Correct Answer: D
Using the ideal gas law, PV = nRT, if volume and pressure double (V₂ = 2V₁, P₂ = 2P₁), then P₂V₂ = nRT₂ gives (2P₁)(2V₁) = nRT₂, or 4P₁V₁ = nRT₂. Since P₁V₁ = nRT₁, T₂ = 4T₁. Given T₁ = 273 K, T₂ = 4 × 273 = 1092 K. Option D is correct.

Q14. The sum of the first n terms of a series is S_n = 3n^2 + 2n. Find the nth term.
A6n + 1
B6n - 1
C3n + 2
D3n - 2
Correct Answer: B
nth term = S_n - S_(n-1) = (3n^2 + 2n) - (3(n-1)^2 + 2(n-1)) = 6n - 1. So, the answer is B.

Q16. The third term of an A.P is 6 and the fifth term is 12. Find the sum of its first twelve terms
A201
B144
C198
D72
Correct Answer: C
T3 = 6
T5 = 12
S12 = ?
Tn = a + (n - 1)d
⇒ T3 = a + 2d = 6 ----- (i)
⇒ T5 = a + 4d = 12 ----- (ii)
Subtract equation (ii) from (i)
⇒ -2d = -6
⇒ d(−6/−2) = 3
Substitute 3 for d in equation (i)
⇒ a + 2(3) = 6
⇒ a + 6 = 6
⇒ a = 6 - 6 = 0
Sn = (n(2a+(n−1)d))/2
⇒ S12 = (12(2×0+(12−1)3)/2
⇒ S12 = 6(0 + 11 x 3)
⇒ S12 = 6(33)
∴ S12 = 198
