The volume of the gas V2 is 66.67 L
<u>Explanation:</u>
<u>Given data</u>
V1= 59.5 L
V2=?
T1= 121K Pa
T2= 108 K Pa
We have the formula,
V1/T1 =V2/T2
Rewrite the formula as,
V2= VI T1/T2
V2= 59.5 L * 121 K Pa/108 K Pa
V2=7199.5 L K Pa/ 108 K Pa
V2=66.67 L
The volume of the gas V2 is 66.67 L
Answer:
Explanation:
There is a trick to this. Counting out the 4 places is easy enough.
Start at the 8 and count to your right. You land on the nine, but that is not quite your answer.
The 7 influences the 9 and the nine gets bumped up which makes it a 10. but you just record the zero part. The 1 gets added to the 2.
That in turn influences the 2 which makes it a three. So your answer is
893.0
The trick is that you must include the 0. You are guaranteeing that you know the accuracy of the fourth place. Weird but true.
It helps just slight to convert this to scientific notation.
8.9297 * 10^2 = 8.930 * 10^2
You get the same rounding problem as discussed above, but it might be a little easier to see.
You get the same answer and you have to go through the same steps.
Answer:
The wavelength decreases
Explanation:
As you go along the EM spectrum from radio waves to gamma rays, the wavelength decreases as the wave's energy and frequency increase.
Answer:
Two significant figures
Step-by-step explanation:
In <em>multiplication </em>problems, your answer can have no more significant figures than the number with the <em>fewest significant figures</em>.
2.05 cm × 32 cm = 65.600 000 00 cm² (by my calculator)
There are three significant figures in 2.05, but only two in 32.
You must round to <em>two</em> significant figures and report the answer as 66 cm².
65.600 000 00 cm² ⟶ 66 cm²
