Types of Energy
Which type of energy is the energy of motion?
Kinetic.
True or false: When energy is transformed, some of the energy is destroyed.
False.
What device is used to measure temperature?
Thermometer.
What are the three methods of heat transfer?
Conduction, convection, and radiation.
Which 2 types of energy does a lit match have?
Thermal and Electromagnetic.
A roller coaster that has reached the top of the hill and is now rolling down the hill is going through which type of energy transformation? BONUS 100 points if you can give the specific type of the first type of energy!
Gravitational potential to Kinetic.
What are the three units of temperature? BONUS 100 points, which one of the three is the SI unit for temperature?
Celsius, Fahrenheit, and Kelvin.
Kelvin is the SI unit for temperature.
Which of the heat transfer methods is demonstrated by the sun melting snow.
Radiation
Which type of energy is particle vibration in a medium?
Sound.
If you turn on a ceiling fan, what type of energy transformation is occurring? (Hint: 1 type into 2 types)
True of false: temperature relies on the quantity of the substance. Explain why or why not.
False. It is the average kinetic energy of the particles. You can have a very large amount of a substance with the same temperature as a very small amount of the same substance.
Which method of heat transfer relies on objects touching?
Conduction.
Which type of energy can travel without a medium and travels in waves?
Electromagnetic.
Describe the law of conservation of energy.
Energy cannot be created or destroyed, it can only be transformed.
Define temperature.
The average kinetic energy of all particles in a substance.
Which way would heat flow if an ice cube were placed on a hot plate?
Heat would flow from the hot plate to the ice cube.
What two types of energy are included in mechanical energy? Give an example of each.
Kinetic and Potential.
Give an example of energy transformation you might see at a beach on a summer day.
Answers will vary.
Which of the following temperatures is the hottest?
5 degrees F
273 K
10 degrees C
10 degrees C.
What is it called when two objects with different temperatures have reached the same temperature because of heat transfer?
Thermal equilibrium.
