Conceptual Fall 2022 Review - Part 3

Melting ice caps will cause the poles to have a (a)   albedo.

• lower
• higher
• same

Why does the leaf appear green?

• Most light wavelengths are transmitted while the green light wavelengths are absorbed

• Most light wavelengths are absorbed while the green light wavelengths are reflected

• Most light wavelengths are reflected while the green light wavelengths are transmitted

• Most light wavelengths are reflected while the green light wavelengths are absorbed

Glass is ​ (a)   to visible light and to ​ (b)   infrared.

• transparent
• opaque
• albedo
• refract

If a graph looks like this, it could be representing a

• positive feedback loop

• negative feedback loop

Since methane is a greenhouse gas and traps heat, it makes...

• the permafrost colder and stops the cycle.

• the permafrost melt even faster, which releases more methane which continues the cycle.

If two objects have different temperatures, heat will flow from the warmer object to the cooler one UNTIL ____________

• one reaches a temperature of zero
• they both have an equal temperature
• one runs out of energy

A material that does not conduct heat well is called a(n)

• conductor

• insulator

What is the definition of CONDUCTION?

• When heat is transferred from objects like rays of light or electromagnetically.
• a  hot liquid or air that  expands, becomes less dense, and rises or becomes more dense, and sinks.
• When heat transfers from objects that are touching.
• When heat transfers through the heater or AC in your house.

You are feeling sick, so you place a thermometer under your tongue to check your temperature. The directions on the box tell you to leave the thermometer there for three minutes before you read your temperature. Why should you wait?

• It takes some time for the thermometer to reach its activation energy.
• It takes some time for the thermometer and your body to reach thermal equilibrium.
• It takes some time for the thermometer to raise your body’s internal energy.
• It takes some time for the thermometer and your body to attain a state of contact.

Heat is defined as

• the transfer of thermal energy from one object to another due to temperature difference

• the temperature of a solid, liquid, or gas

• The kinetic energy of a solid, liquid, or gas.
