Thermo
Heat measures which of the following types of energy?
- Kinetic energy
- Potential energy
Kinetic Energy
3rd law of Thermodynamics
What is no system can reach absolute zero
Entropy does this when temperature decreases.
Decreases
When a substance transitions from a gas to a liquid state of matter.
Condensation
Entropy refers to the amount of _______ in a system.
Disorder, Randomness
When molecules approach zero kinetic energy within a substance.
What is Absolute Zero.
When a substance transitions from a liquid to a gas state.
Vaporization
The phase change in which a substance goes from a gas directly to a solid.
Deposition
When a system increases in temperature, the entropy ________. (Increases/decreases)
Increases
Measure of disorder or lack of organization within a system.
Entropy
When a substance transitions from a liquid to a solid state of matter.
Freezing
Entropy is closely related to what law?
2nd Law of Thermodynamics
True or false: entropy is conserved during a reaction.
False
Heat is a form of this.
Energy
If school is the system, the entropy does this between classes.
Increases
The first law of thermodynamics is a restatement of the law of conservation of energy.
True
What would happen if an object reached absolute zero.
All movement would cease.
If 7200J of heat is put into a heat engine and 3700J of work is done, the heat exhausted by the system is this.
3500J
An engine that does 1600J of work with 2700J of heat added operates at this percent efficiency.
59%
