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.

Which method of analysis does not classify variables as dependent or independent.
Olin [163]

The method of analysis does not classify variables as dependent or independent is cluster analysis.

Cluster analysis is a method that is used to process data in statistics. In cluster analysis, data is classified into groups based on similar characteristics the data share. For example, if cluster analysis is used to group students, students may be divided into clusters based on their gender or class.

An independent variable is the variable that is manipulated by the researcher. It is the variable that is tested to determine its effect on the dependent variable.

The dependent variable is the variable that is being measured in an experiment.
