These are the three ways that heat travels.
What are conduction, convection, radiation
The flow of thermal energy from warmer objects to cooler objects
heat
Rubber, plastic and an oven mitts are examples of
insulators
The energy of moving particles in matter.
thermal energy

convection
How is thermal energy being transferred between the water and a thermometer inside the water
conduction
What happens to the red liquid inside the thermometer as the water in the beaker heats up?(give your answer in two words)
Thermal expansion
How can thermal energy be transferred from one object to another if the objects are not in contact?
by radiation only,
What are the currents of warm and cool air in earth's atmosphere called?
convection currents
Thermal expansion is less noticeable in ___.
solids
represents the average kinetic energy of the particles that make up a material.
temperature
What process occurs in a sidewalk when the temperature decreases
Thermal contraction
the amount of thermal energy required to heat 1 kg of material by 1ºC
specific heat
What does it mean if a material has a low specific heat?
Heat travels easier is a conductor
is the sum of the kinetic energy and the potential energy of the particles that make up a material
Thermal energy
Which is the energy stored in the interaction between objects or particles
potential energy
is an increase in a material’s volume when its temperature increases
Thermal expansion
