Answer:
- The final temperature in the container with Gold is 27.49 ⁰C
- The final temperature in the container with Iron is 33.01 ⁰C
Therefore, the highest final temperature is obtained in the container with Iron.
Explanation:
Q = mcΔT
Where;
Q is the quantity of heat gained or lost
m is the mass of the metals or water
c is the specific heat capacity
ΔT is the change in temperature, T₂ - T₁
T₂ is the final temperature and T₁ is the initial temperature
Heat lost by metals at 100°C is equal to heat gained by water at 25°C
Specific heat capacity of water = 4.18 J/g°C
Specific heat capacity of gold = 0.129 J/g°C
Specific heat capacity of iron = 0.45 J/g°C
⇒For Gold
-20*0.129*(T₂ - 100) = 18*4.18 (T₂ - 25)
-2.58T₂ +258 = 75.24T₂ - 1881
77.82T₂ = 2139
T₂ = 2139/77.82
T₂ = 27.49 ⁰C
⇒For Iron
-20*0.450*(T₂ - 100) = 18*4.18 (T₂ - 25)
-9T₂ +900 = 75.24T₂ - 1881
84.24T₂ = 2781
T₂ = 2781/84.24
T₂ = 33.01 ⁰C
Therefore, the highest final temperature is obtained in the container with Iron.
Answer:
Ending Balance Due = $14,980.106
Total Interest = $780.106
Explanation:
solution
Total Interest and Ending balance due by the U.S. Rule are as given below
so interest is here for 70 day with 12 % of 21000
interest = 0.12 × 21000 ×
interest = $490
so
payment = $2400 - $490
payment = $1,910
and adjusted balance will be after that
adjusted balance = $21,000 - $1,910
adjusted balance = $19,090
and
on 100 day
Interest = 0.12 × $19,090 ×
Interest = $190.9
and
Payment = $4,400 - $190.9
payment = $4209.1
So
adjusted balance = $19090 - $4209.1
adjusted balance = $14,880.9
and interest = $14,880.9 × 0.12 ×
interest = $99.206
so Ending Balance Due will be
Ending Balance Due = $14,880.9 + $99.206
Ending Balance Due = $14,980.106
and
Total Interest = $490 + $190.9 + $99.206
Total Interest = $780.106
