0.60 × collection = 27 cars
collection = 27 cars / 0.60 . . . . divide by the coefficient of the variable
collection = 45 cars
Samuel has 45 cars in his collection.
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

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