177°C
75°C
120°C
Correct answer is A
Parameters given:
V\(_1\) = 200 cm\(^3\); T\(_1\) = 27 + 273 = 300K.
V\(_2\) = 150 cm\(^3\); T\(_2\) = ?
P\(_2\) = 2P\(_1\).
Using the Ideal Gas Equation:
\(\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}\)
\(\frac{P_1 \times 200}{300} = \frac{2P_1 \times 150}{T_2}\)
\(\frac{2}{3} = \frac{300}{T_2}\)
T\(_2\) = 450K.
= 450K - 273K
= 177°C
177 - 27 = 150
That is the amount by which T1 must be increased.

which contains protons and neutrons
which is positively charged
which is massive and can cause deflection of a few projectiles
which is very large and in which close to 98% of projectiles pass undeflected
Correct answer is C
Rutherford's account of Nuclear theory does not include the fact that atoms contain a massive region and cause deflection of from projectiles.
SO\(_3\) is an acidic gas
Acid is usually added to water and not water to acid
The reaction between SO\(_3\) and water is violently exothermic
SO\(_3\) does not dissolve readily in water
