Thermal energy is
The total random kinetic energy of particles in an object.
The total kinetic energy of particles in an object is?
Thermal energy
Thermal expansion is
Thermal expansion is the tendency of matter to change in shape, area, and volume in response to a change in temperature.
Temperature is measured with a
Thermometer
Conduction happens when
Two objects at different temperatures come into the contact with each other
Heat and Temperature are
Very close Related
What Characteristic of large bodies of water explains why the seawater is cooler that the land in the hot afternoon sun?
Water has a higher specific heat than the water
Temperature is an
average
Temperature
is a measure of the average kinetic energy of all particles in an object.
Energy travels to earth through which process?.
radiation
High temperature
The particles are moving fast and have high kinetic energy
Low temperature
The particles are moving more slowly and have a lower kinetic energy.
Heat is
A flow of energy from an object at a higher temperature to an object at a lower temperature.
Insulator
A material that does not transfer energy or electric energy easily.
Conductor
A material that transfers energy or electric charges easily.
Convection
A process by which energy is transferred in gases and liquids occurring when a warm air less dense area of gas or liquid is pushed up by a cooler more dense area of the gas or liquid.
Energy is always transferred through heat from?
A warmer object to a cooler object
Degrees
Are equally spaced units between 2 points
Why does Thermal Expansion happen in solids
Because the particles of solids vibrate more at higher temperatures .
How is energy transferred by convection?
By movement of groups of particles in gases or liquid.
Most common unit of heat measurement
Calorie and Joule
Temperature Scale most commonly used in the rest of the world
Celsius

Collide.
What process causes the warm air to move upward over the land during the day?
Convection
What happens during the day?
Cool air from the sea flows to the land
Conduction is the transfer of energy from a warmer object to a cooler object through?
Direct Contact
Radiation
Energy that travels across distances in the form of electromagnetic waves.
Temperature Scale in United States
Fahrenheit
The particles in a liquid such as a pool move much more _______ than particles in a solid.
Freely
What is the difference between heat and temperature?
Heat is the transfer of energy between objects that differ in temperature. Temperature is a measurement of the average kinetic energy of particles in an object.
In a gas, such as the air around you or in a bubble in water, particles are far apart and move around at ____________
High Speeds
Liquid filled Thermometers measures
How much the liquid expands in a narrow tube as the temperature increases
If the stove heats up the waters temperature will what?
Increase
Warm air is pushed upwards by cooler air during convection because the warm air____
