Need check on temperature (calorimeter) Problems

Click For Summary
SUMMARY

The forum discussion centers on a student's final graded assignment involving calorimetry, specifically applying the principle of conservation of energy, represented by the equation \(\sum\Delta Q = 0\). The student utilized the equation \(0 = \text{Mass(object1)} \times \text{SpecificHeat(object1)} \times (\text{Thermal Equilibrium Temp.} - \text{Original Heat})\) to solve multiple temperature-related problems. The provided answers include temperatures of 20°C, 39.3°C, 84.65°C, and others, indicating a focus on thermal equilibrium calculations.

PREREQUISITES
  • Understanding of calorimetry principles
  • Knowledge of specific heat capacity
  • Familiarity with thermal equilibrium concepts
  • Proficiency in algebraic manipulation
NEXT STEPS
  • Review the concept of heat transfer in calorimetry
  • Study specific heat capacity calculations for different materials
  • Explore advanced calorimetry techniques and applications
  • Practice solving complex thermal equilibrium problems
USEFUL FOR

Students in chemistry or physics courses, educators teaching calorimetry, and anyone preparing for exams involving thermal dynamics and energy conservation principles.

Homework Statement



This is the final graded assignment before finals, and I want to end on a high note and get all of these right.

"See the Picture Attachment"

Homework Equations



Teacher said that \sum\DeltaQ= 0 ---- so ----
0= Mass(object1)*SpecificHeat(object1)*(Thermal Equilibrium Temp. - Original Heat)
So I used this type of equation for each question.

The Attempt at a Solution



I am going to post my answers and if you don't think they are right say something and then I will explain what I was trying to do, because they are algebra intensive questions.

1. 20 degrees C

2. 39.3 degrees C

3. 84.65 degrees C

4. .0507

5. .0335

6. 45.05 degrees C
