તાપમાને ઓકિસજનના અણુઓની ગતિ ઊર્જા તેના \(27^{\circ} C\) તાપમાનના મૂલ્ય કરતા બમણી થશે............. \(^{\circ}\,C\) 

  1. A \(1227\)
  2. B \(927\)
  3. C \(327\)
  4. D \(627\)
Verified Solution

Answer & Solution

Correct Answer

(C) \(327\)

Step-by-step Solution

Detailed explanation

Kinetic energy \(=\frac{f}{2} kT , T\) is absolute temperature. If \(K _1\) is kinetic energy at \(27^{\circ} C\). \(K _2\) is kinetic energy at new temperature \(T\). \(\frac{ K _1}{ K _2}=\frac{ T _1}{ T _2} \Rightarrow \frac{1}{2}=\frac{300}{ T }\) \(T =600\,K\)…
