Detailed Solution for P. Bahadur Test: States of Matter (Old NCERT) - Question 1
  • The average KE and Thermal energy are proportional to absolute temperature.
  • When a substance is heated, some of the absorbed energy is stored within the particles, while some of the energy increases the motion of the particles. This is registered as an increase in the temperature of the substance.

A student forgot to add the reaction mixture to the round bottomed flask at 27 °C but instead he/she placed the flask on the flame. After a lapse of time, he realized his mistake, and using a pyrometer he found the temperature of the flask was 477 °C. What fraction of air would have been expelled out?

Detailed Solution for P. Bahadur Test: States of Matter (Old NCERT) - Question 3

Let the volume of  air in the  flask at 27° C be V1 & that of the same amount of the gas at 477° C be V2.
According to charle’s law
V2/T2  =  V1/ T1   …………………(1)
Volume of gas expelled out = V2 – V1,
Then fraction of the gas expelled out = (V2 – V1 ) / V2 = 1- (V1/ V2)     …………….(2)
Also from equation (1)  V1/ V2 = T1/ T2   …………..(3)
Substituting the values of (3) in (2), we get
Fraction of the air expelled  = 1- T1/ T2 = (T2 – T1)/ T2
= 750- 300 /750 = 0.6
Hence, fraction of air expelled out is 0.6 or 3/5
