Heat & Energy
Stored energy (no motion) due to the interactions between objects is
Potential Energy
What is thermal energy moving from a warmer object to a cooler object.
Heat
A common tool that contains a liquid such as alcohol, which expands and contracts, to make a measurement.
Thermometer
A material that does not conduct heat well is a(n)
Insulator
Conduction works best with this type of matter because the atoms are closely packed together, allowing the particles to collide.
Solid
Energy due to motion
Kinetic Energy
Heat is transferred in three ways. Name the three ways.
What is conduction, convection, and radiation.
Only the US, Belize, Bahamas and a few other countries use this scale which has a freezing point of 32 degrees and a boiling point of 212 degrees.
Fahrenheit
A material that conducts heat well is called a(n)
Conductor
What happens to the temperature of water in a cup when the average kinetic energy of the water particles decreases?
It decreases
The movement of thermal energy from a warmer object to a cooler object
Heat
Soup warming in a pot on the stove is an example of what kind of heat transfer?
Convection
Most countries use this scale which has a freezing point of 0 degrees and a boiling point of 100 degrees.
Celsius
Wood, rubber, and cork are all good
Insulators
The movement of fluids up and down in a cycle because of convection is called
Convection Currents
This represents the average kinetic energy of the particles that make up a material
Temperature
The tip of an iron poker sitting in a fire is an example of what type of heat transfer?
Conduction
Scientists use this scale, which has an absolute 0 and uses no negative numbers. The freezing point of this scale is 273.
Kelvin
The transfer of thermal energy between materials by the collisions of particles is called
Conduction
The particles in a melting ice cube change from a solid to a liquid but their temperature does not change. As the ice melts the particles gain.
(2 energy answers) _______energy and______energy
potential energy and thermal energy
The sum of the kinetic energy and the potential energy of the particles that make up a material.
Thermal Energy
Heat lamps hanging above a buffet table at a restaurant are examples of what type of heat transfer?
Radiation
This is the temperature at which water freezes in Celsius.
Zero degrees Celsius
_______________ are all good conductors
Metals
The amount of thermal energy required to increase the temperature of 1Kg of a material by 1 degree celsius
Specific Heat
