Lab Quiz - Coke Can Calorimetry (Cheeto)

What is the difference about the particles in a hot object from the particles in a colder object?

• The particles in the colder object have greater kinetic energy.

• The particles in the hotter object have greater kinetic energy.

• There is no difference.

What is the first law of thermodynamics?

• Law of relativity

• Law of mass action

• Law of conservation of energy

• Law of conservation of mass

Explain how the heat is transferred between two samples.

• Heat is transferred from hot to cold only.

• Heat is transferred from cold to hot only.

• Heat can transfer from hot to cold AND cold to hot.

• Heat cannot transfer between objects, it can only convert between different types of energy.

Why will it be important to make sure the flame is touching the can when you set up your calorimeter?

• To prevent the loss of most of the heat out to the surroundings and the room.

• To make sure the can gets as much black soot on it as possible.

Observations - Data Table:

Enter the data from your table in order but you'll list it down the row instead of across like it was on your paper.

List your cheeto data in this order:

Initial Mass (food and holder)

Final Mass (food and holder)

Temp 1

Temp 2

Mass of Water

Post Lab 1. Change in temperature:
