Physics 101
friction contact, which means touching. induction, which means non-touching.
Electrons can be transferred from one place to another by the process of
fluids
Energy transfer by convection is primarily restricted to
a warming process
Evaporation is a cooling process and condensation is
is composed of open-structured crystals
Ice has a lower density than water because ice
positive ion
If electrons are stripped from an atom it becomes a
lower the frequency of radiation it emits & longer the wavelengths it radiates
The lower the temperature of an object, the
Mass, specific heat, & change in its temperature
The quantity of heat that a substance can transfer relates to its
small temperature changes
The specific heat capacity is highest for substances that absorb or release large quantities of heat for
8F
Two charged particles repel each other with a force F. If the charge of one of the particles is doubled and the distance between them is halved, then the force will be
quadruples
When the distance between two charges is halved, the electrical force between them
from your finger to the ice
When you touch a cold piece of ice with your finger, energy flows
neutron
Which of these does NOT have an electrical charge?
negatively charged
A positively-charged rod is held near an aluminum can that rests on a dry wood table. If you momentarily touch the opposite side of the can with your finger, the can becomes
iron
Aluminum has a higher specific heat capacity than iron. This means that for equal masses of aluminum and iron, the metal that heats more quickly when the same amount of heat is applied is
closer together
An electroscope is charged positively as indicated by foil leaves that stand apart. As a negative charge is brought close to the electroscope, the leaves become
loosely bound
Charge carriers in a metal are electrons rather than protons because electrons are
higher temperature, but less internal energy
Compared to a giant iceberg, a hot cup of coffee has
for a longer time
Compared with sea-level cooking, in cooking eggs by boiling in mountain regions you should boil the eggs
the same
Particle A has twice the charge of nearby particle B. Compared to the force on Particle A, the force on Particle B is
more than 30 C
Pour two liters of water at 40 C into one liter of water at 20 C and the final temperature of the two becomes
300K
Room temperature on the Kelvin scale
Celsius and Kelvin
Temperature scales that have equal sized degrees
4.19 Joules
The amount of heat needed to raise the temperature of 1 gram of water by 1 C is
radiation
The form of heat transfer that does not depend on a medium is
shorter the wavelengths it radiates
The higher the temperature of an object, the
gain an electron
To become a negative ion, an atom must
ice water
expands when the temperature is lowered
