This indicates the average speed of particle motion in a substance.
What is TEMPERATURE.
100
A rise in temperature will cause a substance to do this.
What is EXPAND.
100
The amount of energy required to change the temperature of one gram of a substance by one degree Celsius.
What is SPECIFIC HEAT CAPACITY.
100
The type of energy transfer that occurs when particles collide with each other.
What is CONDUCTION.
100
We use thermometres to measure temperature becuase these are not adapted to measure temperature.
What are our senses.
200
This has the ability to do work and cause changes.
What is ENERGY.
200
Contraction occurs when the temperature of substance does this.
What is DECREASES.
200
The phase change from Liquid to Gas.
What is EVAPORATION.
200
A type of energy transfer where no matter is moved.
What is RADIATION/RADIANT ENERGY/ELECTROMAGNETIC RADIATION.
200
Early thermometres lacked these.
What are SCALES.
300
The Particle Model of Matter states what three things?
What is 1. Everything is made up of particles. 2. Those particles are always moving. 3. In between those particles is space.
300
This phase of matter will have the largest expansion and contraction.
What is GAS. (Which is what Aidon has, don't sit near him!)
300
The phenomenon where evaporating liquid is used to reduce the temperature of the object it is in contact with.
What is EVAPORATIVE COOLING.
300
The type of energy transfer that occurs when a fluid is heated and cooled.
What is CONVECTION.
300
The Celsius scale is based on these.
What are the PROPERTIES OF WATER.
400
An increase in temperature is caused by an increase in this
What is PARTICLE SPEED.
400
Bridges are made from materilas that expand and contract so they put in an expansion joint to accommodate this. In which season would the joint be the LARGEST.
What is WINTER.
400
To increase the Heat Capacity of an object you would need to do what to it?
What is INCREASE ITS MASS.
400
Conduction can only occur in these two states of matter.
What is GAS AND LIQUID. BONUS: Why?
400
Lord William Thomas Kelvin based his temperature scale on this.
What is ABSOLUTE ZERO
500
What is the difference between HEAT and THERMAL ENERGY.
What is HEAT - the transfer of thermal energy from high energy to low. THERMAL ENERGY - the average speed of all particles in a substance; the total kinetic energy of a substance.
500
Some thug has taken your shoes and thrown them over a low slung power line. They are just out of your reach when you jump for them. In which season should you come back to be able to reach them?
What is SUMMER.
500
The phase change from solid to liquid.
What is MELTING OR FUSION.
500
An object that slows down the transfer of thermal energy.
What is AN INSULATOR OR POOR CONDUCTOR.
500
This is the temperature at which all life ceases to exist.
What is ABSOLUTE ZERO. Bonus: What is it in Celius?
