Particle Attraction
Which state has strongest attraction?
Solid
What measures total energy of particles?
Thermal energy
What transfer requires particle contact?
Conduction
If a material heats slowly and cools slowly, it has a...
High specific heat
This law states the energy cannot be destroyed, only transferred or transformed.
Law of Conservation of Energy
Which state has no bonds?
Gas
What measures average energy per particle?
Temperature
Which transfer uses moving fluid currents?
Convection
When a material is heated it...
Expands
This type of energy is also known as stored energy.
Potential energy
What is required to weaken bond attraction?
Energy
Could a large room-temp kettle have more of this than a small boiling cup?
Yes
Which transfer does NOT require particles?
Radiation
When a material is cooled it...
Contracts
This type of energy is the energy of motion.
Kinetic energy
Which state is less attracted than solids but more than gases?
Liquid
If two beakers, one big and one small, contain water with the same temperature, which cools quicker?
Smaller, it has less thermal energy
What happens when energy bounces off a surface?
Reflect
The only exception to the expansion and contraction rule is...
Water
The formula for work is.
Work = force x distance
Why doesn't the temperature change immediately after energy is added to a material (solid, liquid, gas)?
Energy is absorbed and used to break the bonds before it can be used to increase the temperature.
How do you calculate the average energy?
Add all the energy together, then divide by the amount of particles.
What is the term for energy taken by a material?
Absorb
An example of infrastructure that must consider expansion and contraction when being built is...
railroad tracks, water pipes, roads, etc.
True or false: If I am lifting a box from the ground and moving it somewhere else, I am doing work.
