At an atomic level, when an object is heated up:
The answer is "the kinetic energy of its particles increases."
When heat energy is transferred to objects, the kinetic energy of the particles changes. Heat energy always moves towards equilibrium, meaning that hotter objects transfer their heat to colder objects, and at an atomic level kinetic energy is transferred from faster moving particles to slower moving particles.
There are three types of heat transfer, conduction, convection, and radiation.
Conduction: transfer of heat between two atoms that are touching
Radiation: transfer of heat by electromagnetic waves (light) where particles are not touching
Convection: transfer of heat by the movement of fluids (liquid or gas) where hot particles rise and cold particles sink
Compare your answer with the correct one above
Which of these would require the most thermal energy to warm up?
The answer is 100 kg of steel because more mass will require more energy to bring to a constant temperature.
Compare your answer with the correct one above
Which of these is an example of conduction?
The answer is "A spoon in a cup of hot soup gets warmer."

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.
The answer is greater than because the equilibrium temperature would be higher in the cup with more warm water.

If a piece of iron is very hot, the average kinetic energy of the particles in the iron is:
The answer is "high because the temperature is high."

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?
The answer is 200 mL of cold water because no hot water was added, and the test was not performed.
