Thermal Energy
What is the total kinetic energy of particles in a substance called?
This method of heat transfer happens through direct contact between particles.
What is conduction?
Materials that prevent heat from passing through them are called this.
What are insulators?
Complete this sentence to find the first step of the engineering process: Define the _________ you will need to solve.
What is problem?
This type of energy is related to the motion of particles and can increase or decrease the temperature of an object.
What is kinetic energy?
This term refers to the measure of the average kinetic energy of particles in a substance.
What is the temperature?
The transfer of heat in liquids or gases, where warmer areas rise and cooler areas sink, is called this.
What is convection?
These materials allow heat to pass through easily, like metals.
What are conductors?
After designing a solution, this step in the design process helps you figure out if your design was successful.
What is testing?
When the kinetic energy of an object increases, what happens to its thermal energy?
What is it increases?
What is the term for the transfer of thermal energy from a hotter object to a cooler one?
What is heat?
This type of heat transfer happens through electromagnetic waves, such as the heat you feel from the sun.
What is radiation?
When you are designing a house to keep heat inside, which type of material would you most likely use in the walls?
What are insulators?
This term refers to the materials or limits that you must consider when designing a solution.
What are constraints?
What is true?
True or False: Thermal energy and temperature are the same thing.
What is false?
True or False: Heat always transfers from a colder object to a hotter object.
What is false?
Two objects of the same temperature have a mass of 50g and 500g. Which has more thermal energy?
True or False: After testing your design, you should always modify and improve it based on your results.
What is true?
When the temperature of an object decreases this is what happens to the motion of the molecules.
What is they slow down?
Which of the following is an example of thermal energy in action? A) A stove heating water, B) A fan blowing air, C) A rubber ball bouncing, D) A car moving down the road.
What is A, a stove heating water?
When you use a metal spoon to stir a hot cup of coffee, the heat moves through the spoon by this method.
What is conduction?
Two objects with 50g and 500g are heated up for 10 minutes. Which one will reach the higher temperature?
What is the 50g object because objects with more mass heat up more slowly?
This is the term for what your design needs to do in order to be successful.
What are criteria?
This is the color that will absorb the most energy from the sun's radiation.
What is black?
