How is the combined gas law used to calculate changes in pressure, temperatures, and/or volume for a fixed amount of gas?
nalin [4]

Answer:

Let's start by considering the ideal gas law:

pV=nRT

where

p is the gas pressure

V is its volume

n is the number of moles

R is the gas constant

T is the absolute temperature

This equation can also be rewritten as

\frac{pV}{T}=nR

Now, if we consider a fixed amount of gas, this means that the number of moles (n) is constant. So we can rewrite the equation as

\frac{pV}{T}=const.

And therefore, if we consider a gas undergoing a certain transformation from 1 to 2, we can write

\frac{p_1V_1}{T_1}=\frac{p_2V_2}{T_2}

where 1 indicates the conditions of the gas at the beginning and 2 the conditions of the gas after the process. So, the change in pressure/temperature/volume of the gas can be found by using this equation.

A sound wave produce by a chime 515 m away is heard 1.50 s later.What is the speed of the sound in air?
Marizza181 [45]

Answer:

the seed of the sound in the air is 343.3 m/s

Explanation:

The computation of the speed of the sound in the air is shown below:

As we know that

Speed = Distance divided by Time

So, here speed be 515m

And, the time is 1.50 second

So, the speed of the sound is

= 515m divided by 1.50 seconds

= 343.3 m/s

hence, the speed of the sound in the air is 343.3 m/s
