Exam 2

Chapter 6 -Thermal Mechanics

Definition – Thermal Energy

Definition – Temperature

Temperature scales (why are they needed? how are they defined?  how are they different?)

Know the difference between temperature and thermal energy

What is Absolute Zero? How does it relate to the concept of thermal energy?

Definition - Heat

Definition - Specific Heat Capacity (why is water’s high specific heat capacity important?)

Definition - Thermal Expansion (how is thermal expansion different for liquids compared to solids?)

Thermal expansion of water – why is water unique when it comes to thermal expansion?

Chapter 7 - Heat Transfer and Change of Phase

What does heat transfer mean?

Definition – Conduction

Definition – Convection

Definition – Radiation

What are net-emitters & net-absorbers?

Newton’s Law of Cooling (what does it say? what does it mean?)

What are the phases of matter? What happens when matter changes phase? How is temperature important when it comes to the changing phases of matter?

What is Boiling? How is it affected by atmospheric pressure?

How does energy relate to the change of phase of matter?

Chapter 10 - Waves and Sound

Know the physical properties of waves and how we quantify them (wave speed, amplitude, wavelength, frequency)

What are transverse and longitudinal waves (and how are they different?)

Definitions – compression & rarefaction

The Nature of Sound (what is sound? how does sound travel? what changes its speed?)

What are constructive interference & destructive interference?

What does it mean for sound to reflect? Refract?

Describe the Doppler Effect and how it relates to the movement of the sound source

Chapter 11 - Nature of Light

How are the properties of waves different when it comes to light?

What is the electromagnetic spectrum? What are the different realms of the electromagnetic spectrum?  What makes them different?

Understand Transparent vs. Opaque materials

What are Reflection and Refraction?  How are they different?

What is The Law of Reflection?

What is Color?

What determines the observed color of an object?  How is it related to the selective reflection & selective transmission of light?

How is the nature of white & black determined in physics?
