The final volume of the balloon is 84.75 ml
<u><em>calculation</em></u>
The volume is calculated using Charles law formula
that is V1/T1= V2/T2 where,
V1= 5.00 x10^2 ml
T1= 22.0 °c into kelvin = 22 + 273 = 295 K
V2= ? ml
T2 =0.500 x 10^2 K
make V2 the subject of the formula by multiplying both side by T2
V2 is therefore = T2V1/T1
V2 = (0.500 x 10^2 K x 5.00 x10^2 ml) / 295 K = 84.75 ml
Given:
8.32 J of heat
from 23.2 degrees C to 30.5
degrees C
heat capacity of aluminum is 0.90 J/g-K
Required:
m in grams
Solution:
H
= mCpT
(8.32 J) = m(0.90 J/g-K)(30.5 – 23.2)K
m = 1.27g
