Topic 5 (Energy/ heat transfer) Flashcards
What colored objects gain heat better
Dark colored
The pathway of light as it goes through water changes because of
Refraction
An ice cube is placed in room temp water, what happens to the heat energy?
The ice cube loses energy while the water gains energy
How does PE relate with height?
The higher it is the less potentiol energy, then it suddenly drops and stabelizes
Which process requires most absorption energy of water
Freezing liquid
What type of energy does the sun give to earth?
radiated energy
Which elelment has the highest specific heat?
liquid water
How does energy flow
from hotter to colder
How to calculate HE
HE= Sh x m x t
How do you calculate SH
sh = he/(m x t)
How to calculate Mass with HE
M = he/sh x t)
How to calculate temperature with HE
T= he/(sh x m)
Name the 3 ways to produce energy
conduction, convection, radiation
What is conduction
transferring energy through an object
what is convection
less dense/ warmer stuff go up, more dense/ colder stuff go down
