Thermodynamics Review

Cooking fajitas on a pan is an example of what type of heat transfer?

• Conduction

• Convection

• Radiation

• Entropy

What condition is necessary for heat to flow between two objects?

• They must be of the same mass.

• They must have different temperatures.

• They must be of the same density.

• They must have different conductivities

The first law of thermodynamics, the internal energy of a system can either be increased by adding heat or doing work on the system, while energy is never lost, is a restatement of the

• Principle of entropy

• Law of heat addition

• Conservation of energy

• Law of potential energy

What type of heat transfer is used to heat your marshmallow over the hot air?

• Conduction

• Convection

• Radiation

A reflective blanket is used to insulate people who are cold. What type of heat transfer to the environment is it preventing?

• Conduction

• Convection

• Radiation

As the ice melts, it...

• decreases it's specific heat capacity to change its temperature

• decreases the temperature of water

• absorbs thermal energy, increasing molecular entropy

Which law of thermodynamics best describes why the car cannot be 100% efficient?

• The zeroth law of thermodynamics (Thermal Equilibrium)

• The first law of thermodynamics (Conservation of Energy)
