Forms of Energy
What energy is the sum of an object's kinetic energy and potential energy?
How can heat affect the state of an object?
The added energy (heat) may cause the bonds between particles to break.
Name three fossil fuels.
Coal, Natural Gas, and Petroleum.
What is Thermal Energy?
The total kinetic energy of all particles in a substance.
What energy is kinetic energy caused by the vibration of particles in a medium such as steel, water, or air.
Sound Energy
What temperature in fahrenheit does water freeze?
32
What are the three main ways to transfer energy as heat?
Conduction, convection, and radiation.
Is Solar Energy Renewable?
Yes, it is renewable energy from the sun.
What is a renewable resource?
An energy source that can be easily reproduced or replaced by nature.
What energy is the energy that results from the position or motion of charged particles?
Electrical Energy
What is the (average) body temp?
37
What is the difference between thermal energy and temperature.
Temperature is related to the average kinetic energy of particles, while thermal energy is the total kinetic energy of all the particles.
What does wind energy depend on?
Steady, strong winds that are found only in certain places.
What is Radiation?
The transfer of energy by electromagnetic waves.
Name two types of Potential Energy.
Gravitational Potential Energy and Chemical Potential Energy
What does the kinetic theory of matter explain the motion of particles in?
How is heat related to thermal energy?
Temperature and Thermal Energy are properties of the substance, heat is the energy involved when these properties change.
What is geothermal energy extracted from?
Heat stored within Earth.
What is convection?
The transfer of energy as heat by the movement of a liquid or gas.
What does the law of conservation of energy state?
Name each temperature scale.
Celsius, Fahrenheit, and Kelvin
How is heat measured?
Is Nuclear energy renewable?
No, because minerals in Earth's crust cannot be replaced.
What is conduction?
The transfer of energy as heat from one substance to another through direct contact
