Question

At 27°C temperature, the kinetic energy of an ideal gas is $E_{1}$. If the temperature is increased to 327°C, then kinetic energy would be

• A. (a) $2E_{1}$
• B. $rac{1}{2}E_{1}$
• C. $\\sqrt{2}E_{1}$
• D. $rac{1}{\\sqrt{2}}E_{1}$

Answer 1

(a)

Sol. As temperature changes from 27°C (300 K) to 327°C(600 K) i.e. doubled so kinetic energy also doubled because E µ T.
