energy transfer Flashcards
what is specific heat capacity
the anount of energy needed ti raise the temperature of one kilogram of a substance by one degrees celcius
what is the unit for the change in thermal energy
Joules
what piece of equipment would you use to measure the change in thermal energy
Joulemeter
what is the unit for mass
kilograms
what piece of equipment would you use to measure mass
balance
what is the jnit for temperature change
degrees
what ouece of equipment would you use to measure temperature change
thermometer
what factors affect the rate of cooling of a building
the thickness and thermal conductivity of its walls
what is a conductor
the process which energy is transferred through a material
what materials are good conductors
metals
what is an insulator
materials that are poor conductors
what materials are good insulators
non metals and air
how do insulators reduce unwanted energy loss
insulation which has low thermal conductivity so less energy is transferred by conduction
what happens to energy that is wasted in a home
it is dissipated into the environment in the form of thermal energy
