Answer:
When the volume will be reduced to 2.50 L, the temperature will be reduced to a temperature of 230.9K
Explanation:
Step 1: Data given
A sample of sulfur hexafluoride gas occupies a volume of 5.10 L
Temperature = 198 °C = 471 K
The volume will be reduced to 2.50 L
Step 2 Calculate the new temperature via Charles' law
V1/T2 = V2/T2
⇒with V1 = the initial volume of sulfur hexafluoride gas = 5.10 L
⇒with T1 = the initial temperature of sulfur hexafluoride gas = 471 K
⇒with V2 = the reduced volume of the gas = 2.50 L
⇒with T2 = the new temperature = TO BE DETERMINED
5.10 L / 471 K = 2.50 L / T2
T2 = 2.50 L / (5.10 L / 471 K)
T2 = 230.9 K = -42.1
When the volume will be reduced to 2.50 L, the temperature will be reduced to a temperature of 230.9K
The answer for 1/0.00032 in standard scientific notation is 3.125 * 10^3.
<u>Explanation</u>:
For conversion of the given number in scientific notation follow
a * 10^b
The steps to see how 3,125 written in scientific notation as follows.
Step 1
To find a, The number is moved right to one decimal place.
Original Number: 3,125
New Number: 3.125
Step 2
Now, to find b, Find the decimal count on the right side.
New Number: 3 .1 2 5
Decimal Count: 1 2 3
There are three places found.
Step 3
Now we can reconstruct the number into scientific notation.
The Scientific notation is: a x 10^b
a = 3.125
b = 3
Now writing the whole thing:
3.125 x 10^3
Step 4
Check your work:
10^3 = 1,000 x 3.125 = 3,125.
The thermal energy heats up the energy in the ice cube causing it to melt and cool off the drink slightly.
