Middle School Physical Science › Determine the relationships between energy transfer and change in kinetic energy
You are doing an experiment where you pour different amounts of hot water into the 200mL of cold water and measure the final temperature. The purpose of a “control” in an experiment is to see what would happen if you did NOT do a test. If we are testing how the volume of warm water effects energy transfer, which cup is our control?
Fill in the blank in the statement below:
If more hot water was added to a cup than cold water, the final temperature of the solution would be _________ in comparison to a cup with equal parts cold and hot water.
Which of these is an example of radiation?
At an atomic level, when an object is heated up:
In conduction, heat energy always moves:
Which of these would require the most thermal energy to warm up?
If a piece of iron is very hot, the average kinetic energy of the particles in the iron is:
Which of these is an example of convection?
Which of these is an example of conduction?
What is the relationship between kinetic energy and thermal energy?
