Heat Transfer
"Feeling warm near a campfire is an example of this type of heat transfer."
"Radiation"
"This type of energy, also known as heat, is shown by an object’s temperature."
"Thermal Energy"
The Law of Conservation of Energy:
"Energy can't be created or .....?"
"Destroyed"
"Which Energy is commonly used by technology such as phones and computers?"
"Electrical Energy"
"This type of energy, like solar power, is considered renewable because it naturally replenishes."
"Renewable Energy"
"A metal spoon heating up in a bowl of soup demonstrates this process of heat moving through direct contact."
"Conduction"
"The energy of a moving ball or a running person is known by this name."
"Kinetic Energy"
"When you drop a ball, its stored energy at the top is converted to this form as it falls."
"Kinetic Energy"
"The energy stored in food and other molecules".
"Chemical Energy".
"Coal is an example of this type of energy source because it is finite and cannot be replenished on a human time scale."
"Non-Renewable Energy"
"Boiling water rising in a pot is an everyday example of this heat transfer process where heated molecules move within fluids."
"Convection"
"Energy stored in a stretched rubber band is an example of this kind of potential energy."
"Elastic Energy"
"Friction causes kinetic energy to be changed into ______ energy?"
"Heat Energy"
"To reduce the loss of thermal energy in our homes we can add _______ inside the walls?"
"Insulators / Insulation"
"Name two fossil fuels that have been commonly used for energy production."
"What are coal and oil?"
"In a pan on a stove, conduction, convection, and radiation all occur. Name one of these processes and briefly explain its role in heating the pan."
Conduction OR Convection OR Radiation)
"When an object is high above the ground, it stores this type of potential energy due to gravity."
"Gravitational - Potential Energy"
"Potential Energy is also known as ________ energy?
(Energy waiting to be converted and used)"
"Stored"
"What renewable energy source would you use if you were staying in Africa?"
"Solar Power" (It's sunny).
"What is an advantage of choosing Renewable energy sources?"
"Prevents Global Warming"
"In an experiment, a black jar placed in the sun gets hotter than a white jar. Name the heat transfer process responsible and explain why this happens using the concepts of radiation and absorption."
"Radiation, because the black jar absorbs more radiant energy than the white jar."
"Energy released during nuclear reactions inside a reactor comes from this form of energy stored in the atom’s core."
"Nuclear Energy"
"If a ball bounces, name 3 types of energy that the ball's potential energy is converted to."
"Sound, Thermal, Kinetic".
"What is an advantage of using Fossil Fuels - rather than renewable energy?"
"Cheaper to use for electricity".
"Why do some counties prefer using Nuclear power over alternative sources?"
"Cheaper, get a lot of energy from a small amount of material".
