(A – 2) and (Z – 2)
(A + 4) and (Z + 2)
(A– 4) and (Z+2)
(A+ 4) and (Z – 2)
(A – 4) and (Z – 2)
Correct answer is E
Let the element be S and the element formed after emission be X.
\(\implies ^{A} _{Z}S \to ^{4} _{2}He + X\)
\(\therefore X = ^{A - 4} _{Z - 2}X\).
M(C1 ÷ C2) x T
ML
L
M(C1 + C2) × T ÷ ML
ML(C1 + C2 ÷ 2) × T

600°C
Correct answer is D
\(\frac{V_{1}}{T_{1}} = \frac{V_{2}}{T_{2}}\)
Given \(V_{2} = 2V_{1}\)
\(T_{1} = 27°C + 273 = 300k\)
\(\frac{V_{1}}{300} = \frac{2V_{1}}{T_{2}}\)
\(\frac{1}{300} = \frac{2}{T_{2}} \implies T_{2} = 600k or 327°C\)
