Anya placed an ice cube on the sidewalk on a warm day. The ice cube soon melted to form a puddle. What process caused the ice cube to melt?

• Heat transferred through the ice cube by convection.

• Heat transferred from the air to the ice cube by radiation.

• Heat transferred from the air by radiation and the pavement by conduction.

• Heat transferred through the ice cube into the pavement by conduction.

Jake is wearing gloves while he gets a hot pan out of the oven. Which best explains why Jake needs to wear gloves while he is carrying the hot pan?

• The gloves protect his hands from convection heat in the hot pan.

• The gloves protect his hands from heat that is radiated through the hot pan.

• The gloves protect his hands from heat that is conducted through the hot pan.

• The gloves protect his hands from heat that enters the pan from the surrounding air.

James measured the temperature outside his house everyday for 2 months. He observed that on days the sky was mostly cloudy, the temperature was an average of 9 degrees cooler than days the sky was mostly sunny. Which best describes the reason for this pattern?

• The clouds blocked radiation from the sun, causing cooler temperatures.

• The clouds blocked conduction from the sun, causing cooler temperatures.

• The clouds allowed more radiation from the sun to reach the Earth’s surface.

• The clouds allowed more conduction from the sun to reach the Earth’s surface.

A dark-colored wall becomes warm when the sun shines on it. After sunset, a person standing a meter away can feel warmth from the wall. How does heat transfer from the wall to the person?

• radiation

• conduction

• convection

• insultation

Joe wants to slide down on a sunny day, but the slide is too hot. Which is most likely the reason for the slide being hot?
