A fixed container containing an ideal gas is heated. The pressure of the gas increases because:_________
evablogger [386]

A fixed container containing an ideal gas is heated. The pressure of the gas increases because the molecules move faster.

You can speed up the motion of the molecules in a gas by heating it. The pressure will rise and there will be greater impacts on the container's walls.

The container walls are pressed against by the combined force of the collisions. The energy you provide when you heat the gas makes the gas's particles more kinetically energetic and put more pressure on the container.

As the temperature rises, the pressure must as well since pressure is the force the particles per unit of area exert on the container.

In 1993, Ileana Salvador of Italy walked 3.0 km in under 12.0 min. Suppose that during 115 m of her walk Salvador is observed to
dexar [7]

Answer:

t = 25 seconds

Explanation:

Given that,

Distance, d = 115 m

Initial speed, u = 4.2 m/s

Final speed, v = 5 m/s

We need to find the time taken in increasing the speed.

We know that,

Acceleration, a=\dfrac{v-u}{t} ....(1)

The third equation of kinematics is as follows :

v^2-u^2=2ad\\\\\text{Put the value of a in above equation}\\\\v^2-u^2=2\times \dfrac{v-u}{t}\times d\\\\\because (a^2-b^2)=(a-b)(a+b)\\\\(v-u)(v+u)=\dfrac{2\times (v-u)d}{t}\\\\t=\dfrac{2d}{v+u}\\\\\text{Putting all the values}\\\\t=\dfrac{2\times 115}{4.2+5}\\\\t=25\ s

Hence, it will take 25 seconds to increase the speed.
