Answer:
The volume of the balloon when it is fully cooled by my refrigerator is
2.75liters
Step-by-step explanation:
we are expected to apply Charles law in this problem and solve for the final volume V2
the expression for Charles law is give as
V1/T1=V2/T2
given data
V1, first volume
= 0.5 liters
V2, second volume
=?
T1, first temperature
= 40 ◦Celsius.
T2, second temperature
=220 °C
applying the formula we have
0.5/40=V2/220
V2=(0.5*220)*40
V2=110/40
V2=2.75liters
Answer:
about %55
Step-by-step explanation:
You can find the answer by dividing the percent number by the whole number:
74/86 ≈ %55
<h3>
Answer: 15 feet</h3>
Explanation:
x = length of the actual car in inches
5% of x = 9 inches
0.05x = 9
x = 9/(0.05)
x = 180 inches
Divide by 12 to convert from inches to feet.
180 inches = (180/12) feet = 15 feet
