Studied by 29 peopleuse the figure on the right to answer the question. why do you think the double plan window above contains an air? explain
air is good insulator of thermal energy. it slows down the transfer of heat
what is the role of density in the formation and movement of convection currents ?
warm less dense water rises and the cold more dence water sinks
thermal expansion
the expanding of matter when it is heated is known as thermal expension .
what causes damage
the amount of force , speed , direction , mass , material
temperature
a measure of how hot or cold something is with respect tona reference point
celsius scale
water freezes at 0 degrees and boils at 100 degrees
density
the measure of how much most of a substance is contained at a given volume
absolute zero
the lowest temperature possible, the kinetic energy of individual particles is zero
fahrenheit scale
water boils at 212 degrees water freezes 32 degrees
convection
is a type of heat transfer that occurs only in fluids, such as water and air
conduction
transfers heat from one particle of matter to another within an object or between two objects
thermal conductor
a material that conducts heat well
thermal insulator
materials that do not conduct heat well
heat
the transfer of thermal energy from a warmer to a cooler object.
kelvin scale
the temperature scale on which zero is the temperature at which no more energy can be removed from matter.
radiation
is the transfer of energy by electromagnetic.
thermal energy
thermal energy is the total energy of all the particles is an object
temperature and mass
two factors that determine an objects thermal energy
thermal energy in an object is defined as
the total energy of particles in an object
how is heat transferred
it is transferred from warmer areas to cooler areas by conduction, convection, and radiation
specific heat
to change the temperature of different objects by the same amount, different amounts of thermal energy required
energy change
mass, specific heat, temperature change
what is the way material respond to heat
conductor or insulators
