When the temperature of an ideal gas is increased from 27^ C to 927^ C , the kinetic energy will be
Options
- Asame
- Beight times
- Cfour times
- Dtwice
Correct answer
C. four times
Step-by-step solution
Increase in temperature of ideal gas from 27^ C to 927^ C Increase in K E= 3 2 R T aligned T₁ & =27+273 & =300 ~K T₂ & =927+273 =1200 ~K K E₁ & = 3 2 R 300 ~K K E₂ & = 3 2 R 1200 ~K So, K E₂ K E₁ & = 3 2 R 1200 ~K 3 3 R 300 ~K =4 aligned Hence kinetic energy is increased four times.
