Answer:

more reliable results

Explanation:

hey there,

< More data is more reliable results as you can see even more about the experiment you are doing! If you only know one other scientist that had done the experiment and it worked for him, then that's not enough data, but if you have thousands of scientists that were able to do the experiment correctly, you will have a more reliable and correct result since now you have more data. >

Hope this helped! Feel free to ask anything else.

Perform the following

docker41 [41]

Answer:

8.73

Explanation:

when you are adding or subtracting numbers, the sigfig (significant figure) is based on how many numbers after the decimal. with this info, we can see that 15.67 has 2 sigfigs and 6.943 has 3 sigfigs. when you subtract normally, you would get 8.727, which has 3 sigfigs, so you would round the last 7 up to get 8.73 with 2 sigfigs!

also it is to 2 sigfigs because we know that we go by the least number of sigfigs. hope this helped!

A balloon containing a sample of helium gas measures 1.50 L at a temperature of 25.0°C is placed in a refrigerator at 36.0°F. Ca

Fiesta28 [93]

Answer:

1,39 L

Explanation:

Charle's Law states that the volume of a fixed amount of gas maintained at constant pressure is directly proportional to the absolute temperature of the gas, for a constant amount of gas we can write:

$\frac{V1}{T1}=\frac{V2}{T2}$

As the pressure of the balloon doesn't change, we can use Charle's Law to solve the problem. Firs we change the given temperatures to absolute temperature units ( °K), using the following relations:

°K=273+°C

°K=5/9(°F-32)+273

Therefore:

V1=1.5 L, T1=273+25=298°K

V2=?, T2=5/9(36-32)+273=275,2°K

$V2=\frac{V1T2}{T1}=\frac{275,2*1,5}{298}=1,39L$

The new volume of the balloon is 1,39 L.
