If a volume of air is warmed, it expands and tends to
Butoxors [25]

if a volume of air is warmed it expands due to increased translational kinetic energy as it expands it will start to cool.

<h3>When does temperature increase volume?</h3>

We can then conclude that at constant pressure, temperature and volume are directly proportional: temperature increases, volume increases; decrease temperature, decrease volume.

In this case, the higher the temperature, the greater the kinetic energy that acts on the molecules of this gas, so when the gas expands, these molecules find more space and collide less, which will cause the gas to cool.

An auto race takes place on a circular track. A car completes one lap in a time of 25.0 s, with an average tangential speed of 5
ludmilkaskok [199]

Answer:

(a) Angular speed will be 0.2512 rad/sec

(b) Radius will be 213.375 m

Explanation:

We have given time to complete 1 lap = 25 sec

We know that 1 lap = 2\pi radian

(a) So angular speed =\frac{2\pi }{25}=\frac{2\times 3.14}{25}=0.2512rad/sec

(B) Tangential velocity is given as v = 53.6 m/sec

We know that tangential velocity is given by

v=\omega r

So radius r=\frac{v}{\omega }=\frac{53.6}{0.2512}=213.375m
