Question

The temperature of an ideal gas is increased from 140k to 560k

Answer 1

Answer:

The temperature of an ideal gas is increased from 120 K to 480 K. If at 120 K, the root mean square speed of gas

Answer 2

$\huge\star{\underline {\mathtt{\red{αղsաҽɾ}}}}$

The root mean square velocity is directly proportional to the square root of temperature.

Thus when the temperature increases from 140 K to 560 K, the root mean square velocity increases from u to

$\sqrt{ \frac{560}{140} } u = 2u$
