Which surface usually feels warmer at the same room temperature: carpet or tile?

Carpet. Carpet insulates and doesn't conduct heat away quickly.
Which object is usually warmer after sitting near a heater: a blanket or a metal pan?

A blanket. Blankets trap and hold heat better than metal.
Which surface usually feels warmer in the same room: foam mat or concrete sidewalk?

Foam mat. Foam insulates while concrete conducts heat away quickly.
Which option usually feels warmer: tile floor or carpet in the same room?

Carpet usually feels warmer. Carpet insulates and holds heat better than tile.
Which option is usually cooler in sunlight: blacktop pavement or grass?

Grass. Grass stays cooler than dark pavement which absorbs more heat.
Which surface is usually cooler: a shaded sidewalk or a sunny sidewalk?

A shaded sidewalk. Shade blocks direct sunlight that heats surfaces.
Which option is warmer: the side of a playground slide in sunlight or the same slide in shade?

The slide in sunlight. Direct sunlight heats playground equipment.
Which option is usually warmer to the touch: a plastic cup or a metal cup in the same room?

Plastic cup. Plastic doesn't conduct heat away as quickly as metal.
Which surface is most likely to feel cooler in sunlight: white paper or black paper?

White paper. White reflects sunlight while black absorbs it.
Which surface is usually cooler: a wet towel or a dry towel in the same place?

A wet towel. Water evaporating from wet surfaces removes heat.
Which place usually makes a surface feel cooler: shade or direct sunlight?

Shade. Shade blocks sunlight so surfaces don't heat up as much.
Which heats faster in sunlight and often feels warmer: a dark surface or a light surface?

A dark surface. Dark colors absorb more light energy and convert it to heat.
What word describes a surface that feels like it has less heat: warmer or cooler?

Cooler. Cooler means having less heat energy than something else.
Identify the best action if a surface feels too hot when you touch it.

Stop touching it and move your hand away. Moving away quickly prevents burns from hot surfaces.
