Heat Flashcards
1
Q
What is heat
A
The flow of energy due to temperature differnces(warmer to cooler)
2
Q
What is temperature
A
Average kinetic energy of all the particles in the object
3
Q
What determines the temp of an object
A
The atoms and the mass
4
Q
How is heat transferred
A
Conduction
Convection
radiation
5
Q
What is conduction
A
Process that moves energy from one to another when touching
Conductors good
Insulators bad
Continues until temps are equal
6
Q
What is convection
A
The movement of gas or liquid particles, the rise of warm sink of cool. Cycle while there are temp differences.
7
Q
What is the formula for kinetic energy
A
EK=1/2mv2
8
Q
What is radiation
A
The energy transferred by electromagnetic waves, all objects radiate energy, can transfer through empty space
