HELP PLS Ideal gas pressure increases 10 times, but absolute temperature decreases 14 times. How much times does the volume of gas changes if its mass does not change?

1/140 times

Explanation:

The ideal gas law formula is stated as :

PV = nRT

where ;

P= pressure

V=volume

n=amount of substance

R=ideal gas constant

T= temperature

In this equation, both pressure and volume are directly proportional to temperature;

So if;

PV = nRT i

Increasing pressure by 10 times and decreasing absolute temperature by 14 times will give;

10 PV = n*R* T/14

Making V the subject of the formula as;

14* 10 * PV = n*R*T

140 PV = n*R*T

V= n*R*T / 140 Pii

Taking n and R to be constants then divide ii by i

T/140 P / T/P

T/140 P * P/T

1/140 times

air exerts forces on falling objects near earth’s surface.

explanation:

the term 'free falls' refer to object that are falling towards the earth, in a situation in which gravity is the only force acting on the object.

for an object in free fall, the acceleration is constant (g, the gravitational acceleration), and so the velocity of the object constantly increases.

for objects near earth's surface, there is always another force acting on the object: the resistance due to the air. this force is opposed to the direction of fall of the object, and it is proportional to the velocity of the object, so as the object falls down, this force increases up to a point when it balances the force of gravity, and the object continues its motion at constant velocity (called terminal velocity). since in this case gravity is not the only force acting on the object, we are not in a situation of free fall.
