Thermal energy
what is the measurement of average kinetic energy in a substance called
temperature
What is the top part of a transverse wave called?
Crest
which type of bond do atoms share 2 or more pairs of electrons?
covalent
When a temperature curve (Temperature vs heat added) curves upward, is the added energy apparent in the movement of the molecules
yes
potential energy is energy due to ____________
position
Can heat be gained or lost, or just thermal energy?
Just thermal energy
What is the distance from crest to crest of a wave called
wavelength
which type of bond shares electrons between more than 2 atoms
metallic bond
In which part of the heating curve would we most likely observe atoms in 2 phases of matter?
Phase change:Flat parts
What force gives objects on earth potential energy?
gravity
Can thermal energy be absorbed or given off in a chemical reaction? give an example
Yes. Baking soda and vinegar reaction absorbs thermal energy
which wavelengths of Electromagnetic energy do cell phones communicate with?
microwaves
Which type of bond betweeen two atoms is caused by a difference in electrical charge
ionic bond
What does the flat part of a temperature curve indicate
Phase change is occurring
What force causes chemical bonding
electromagnetic forces primarily
Name the three types of thermal transfer
Radiation, convection, and conduction
If a sound wave hits a wall, what word describes how often each crest of the wave hits the wall
frequency
Why are metals strong?
They can bank their electrons between atoms. This banked negative charge attracted to the positive nucleus charges creates a strong bond
Are all the atoms the same temperature when water boils
No. There are some atoms hotter, and some cooler, the temperature is just an average
If I am measuring kinetic energy, I am measuring the ________________ of the atoms
speed, or force of the atom collisions
Does thermal energy travel as an electromagnetic wave
yes.
What type of wave carries wifi signals?
high frequency radio waves
What is it called when atoms share more than one pair of electrons
a double or triple covalent bond
What happens to added energy during the flat parts of the heating curve
It goes into loosening up the molecules' bonds
In which phase of matter is kinetic energy highest
plasma
