PS 3-2, 3-2, 3-4, 3-5 Review

A scientist performs an activity to study how different materials are affected by heat. She fills a container with water at 80°C and places four rods made of different materials in the container. The scientist mounts a wax ball of the same size on each rod, as shown and records the time for each wax ball to melt completely.

Which materials are the 2 BEST conductors?

• Y

• W

• X

• Z

A student fills a plastic tube with water at 10°C and places caps at the ends to prevent the water from leaving the tube. The student submerges the tube in a bucket of warm water at 35°C. After 20 minutes,the student observes that the tube has the same shape and records that the temperature of the water in the tube rises to 22°C.

What will happen if the student repeats the activity with a METAL tube instead of the PLASTIC tube?

• The metal tube will break when put in the warm water because the tube absorbs radiation from the warm water.

• The metal tube will bend when put in the warm water because the tube is insulated from the warm water.

• The temperature of the water in the metal tube will rise much faster because metal is a better conductor of heat than plastic.

• The temperature of the water in the metal tube will rise at the same rate because the starting temperature of the water remains unchanged.
