Bell Ringer: Energy.

What type of energy did Mia’s sled have before she pushed off?

• Kinetic energy

• Potential energy

• Thermal energy

• Mechanical energy

What type of heat transfer caused the snow beneath Mia’s sled to warm up as she moved downhill?

• Convection

• Conduction

• Radiation

• Evaporation

Mia’s gloves helped keep her hands warm because they acted as:

• Conductors, allowing heat to pass through easily

• Radiators, producing their own heat

• Insulators, reducing heat transfer

• Convection currents, circulating warm air

Why did the metal bench feel much colder than Mia’s gloves, even though both were outside in the same weather?

• The bench was at a lower temperature than the gloves

• The bench conducted heat away from her hand faster than the gloves

• The gloves absorbed heat from the sun while the bench did not

• Mia’s body temperature dropped, making the bench seem colder

Which of the following is an example of convection in the passage?

• The snow melting beneath the sled due to friction

• The cold air moving around Mia’s body, making her shiver

• The metal bench feeling cold to the touch

• The sled accelerating as it moves downhill
