If the pressure on a gas sample is tripled and the absolute temperature is quadrupled, by what factor will the volume of the sam

antoniya [11.8K]

Answer:

b. 4/3

Explanation:

Given data

Initial pressure: P₁

Initial volume: V₁

Initial temperature: T₁

Final pressure: P₂ = 3 P₁

Final volume: V₂

Final temperature: T₂ = 4 T₁

We can find by what factor will the volume of the sample change using the combined gas law.

$\frac{P_{1}.V_{1}}{T_{1}} =\frac{P_{2}.V_{2}}{T_{2}}\\\frac{P_{1}.V_{1}}{T_{1}} =\frac{3P_{1}.V_{2}}{4T_{1}}\\V_{1} =\frac{3V_{2}}{4}\\V_{2}=4/3 V_{1}$

Do the following problem using significant figures. 4.5 cm x 2000.0 cm x 4 cm = I cm^3

Anon25 [30]

Given :

Measurements $4.5\ cm\times 2000.0\ cm\times 4\ cm$ .

To Find :

The multiplication using significant figures .

Solution :

We know , the least number of significant figures in any number of the problem determines the number of significant figures in the answer.

So , significant figure( S.F) in 4.5 cm is 2 .

S.F in 2000.0 cm is 5 .

S.F in 4 cm is 1 .

So , minimum S.F is 1 .

Therefore , S.F of their product is 1 .

Now , multiplying them we will get :

$M=4.5\times 2000.0\times 4 \ cm^3\\\\M=36000\ cm^3$

Now , converting 36000 in 1 significant digit .

First we will write it in exponential 2 S.F form.

$3.6\times 10^4 \ cm^3$

Now , to convert 3.6 into 1 S.F we should round off this .

So , round off 3.6 we will get 4 .

Therefore , The multiplication using significant figures is $4\times 10^4\ cm^3$ .

Hence , this is the required solution .
