B Review Flashcards

Front

What is thermal physics?

Back

The branch of physics that deals with the relationships between heat and other forms of energy.

Front

Define the greenhouse effect.

Back

The warming of Earth's surface due to the trapping of heat by greenhouse gases in the atmosphere.

Front

What are the main greenhouse gases?

Back

Carbon dioxide (CO2), methane (CH4), nitrous oxide (N2O), and water vapor (H2O).

Front

Explain Ohm's Law.

Back

The relationship between voltage (V), current (I), and resistance (R) in an electrical circuit, expressed as V = IR.

Front

What is the unit of temperature in the SI system?

Back

Kelvin (K).

Front

What is the specific heat capacity?

Back

The amount of heat required to raise the temperature of one kilogram of a substance by one degree Celsius.

Front

What is the formula for calculating heat transfer?

Back

Q = mcΔT, where Q is heat transfer, m is mass, c is specific heat capacity, and ΔT is the change in temperature.

Front

What is thermal equilibrium?

Back

The state in which two objects in contact do not exchange heat, meaning they are at the same temperature.

Front

What is resistance in an electrical circuit?

Back

The opposition to the flow of electric current, measured in ohms (Ω).

Front

What is the unit of power in an electrical circuit?

Back

Watt (W), which is equal to one joule per second.
