Suppose that 3. 33 g of acetone at 25. 0 °c condenses on the surface of a 44. 0-g block of aluminum that is initially at 25 °c.
Vlada [557]

The final temperature on the block is 25 degrees.

Heat is a form of energy. This question shows that energy is transferred from the acetone to the metal block.

Data given;

  • M1 = 3.33g
  • T1 = 25 degrees
  • M2 = 44g
  • T2 = 25 degree
  • C1 = 124.5 J mol K
  • C2 = 0.89 J/g K
<h3>Heat Transfer</h3>

Applying the principles of heat transfer,

Heat loss = Heat gain

m1c1(T1 - T3) = m2c2(T3 - T2)\\3.33*124.5*(25.0 - T3) = 44*0.89*(T3 - 25)\\10364.625 - 414.585T3 = 39.16T3 - 979\\10364.625+979 = 414.585T3 +39.16T3\\11343.25 = 453.745T3\\T3 = \frac{11343.25}{453.745} \\T3 = 24.999\\T3 = 25

From the calculation above, the final temperature on the block is 25 degrees.

What is one financial goal that you have? How do larger economic factors influence your pursuit of this goal?
saveliy_v [14]
A financial goal that I have is to have a well-paying job as I get out of high school so I can afford to go to a University of my choice. This way I won't be in crippling debt and have to take out massive student loans. However, inflation as well as taxes will influence this. Income taxes will force me to have to give up some of my hard-earned money, which will significantly reduce the amount of money I actually make.
I hope this helps! :D If so, will you add it as the brainliest? Thanks! :D
