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

Which of the following has stored elastic potential energy?
a trampoline that is not being used
a rubber ball that is falling from a height
a spring sitting at rest on the top of a table
a rubber band stretched between two fingers
It takes 3 seconds for the arrow to hit the target after it is released. Which data table best explains the transformation of energy?
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.
