If 1023 gas molecules each having a mass of 1a–25 kg, placed in a 1 Lcontainer, moving with rms speed of 105cm/sec. then the total KE of gasseous molecules and pressure exerted by molecules, respectively are :

(1) 10 kJ, 3.33 × 106 Pa

(2) 5 kJ, 3.33 × 108 Pa

(3) 10 kJ, 3.37 × 107 Pa

(4) 5 kJ, 3.33 × 107 Pa
