The temperature of a gas placed in an open container from `27^(@)C` to `227^(@)C`. The prevent of the original amount of the gas expelled from the container will be:A. 20B. 40C. 60D. 80 |
|
Answer» Open container `rArr P & V` is constant So, nT=constant `n_(i)(300)=n_(f)=(500)` `n_(f)=(3)/(5)n_(i)` `n_(i)=n_(f)+n_("escape")` `n_("escape")=(2)/(5)n_(i)rArr 40%` |

5 mole of an ideal gas change it's volume from 10 L to 20 Lit. reversible isothermally at 300 K then work done by gas is.......KCal. [Given R = 2 Cal] |
|
Answer» Correct answer is (2) For isothermal reversible process W = -2.303 nRT log (v2/v1) = -2.303 x 5 x 2 x 300 log (20/10) = -2072.7 cal = -20727 x 103 cal = -2 K Cal = |W| = 2 K cal |
|

Prove that 1 newton=10 to the power 5 dyne |
|
Answer» 1 N force is the force which when applied on a 1 kg mass results to an acceleration of 1 m/s2 in the body. 1 dyne force is the force which when applied on a 1 gram mass leads to an acceleration of 1 cm/s2 in it. 1 kg = 1000 gram and 1 m = 100 cm => 1 N = 1(kg)(m/s2) = (1000 gram)(100cm/s2) = 105 dyne. |

|
Answer» The heart of an athlete works harder when other muscles in the body pump more blood to the heart. The major muscles of the legs have large veins that fill during relaxation stage of the movement. The muscle contraction in the active movement pushes the blood back into the circulatory system. The heart of an athelete pump more blood per beat. Maximum heart beat rate as well as resting heart beat rate falls below the pace of the average heart beat. |
