Energy
The ability to do work.
What is energy?
The thermal energy of a substance depends on these two things.
What are mass and temperature?
When the temperature change in a substance is not very great and the substance does not change state, the particles may only move faster and farther apart.
What is thermal expansion?
Heat transfer that occurs when particles bump into each other but do not change locations.
What is conduction?
A resource that is no longer forming today and once it is used completely is gone.
What is a nonrenewable resource?
Electricity, Sound, and Radiant are examples of this.
What is kinetic energy?
The total kinetic energy in the particles of a substance.
what is thermal energy?
The amount of thermal energy needed to raise the temperature of 1 gram of water 1 degree Celsius.
What is a calorie?
The transfer of thermal energy from one substance to another.
What is heat?
Any substance that releases energy when it is burned.
What is fuel?
The energy that an object or substance has because of its position or condition.
What is potential energy?
The measure of the average kinetic energy of the particles in a substance.
What is temperature?
Heat naturally moves from __________ objects to ___________ objects.
What is warmer to cooler?
Transfer of thermal energy that occurs when particles move from one place to another.
What is convection?
These types of fuel were formed during the Genesis flood when the remains of dead plants and animals were quickly covered.
What are fossil fuels?
Gravity, chemical, and nuclear are all examples of this.
What is potential energy?
Zero on the Kelvin scale is called this?
What is Absolute Zero?
This causes the heat that occurs when a spacecraft launches or lands.
What is friction?
Heat transfers that occur when no particles are present to carry the energy such as the sun's energy heating the earth.
What is radiation?
These are the three fossil fuels.
What is coal, crude oil, and natural gas?
Energy that an object or substance has because of its motion.
What is kinetic energy?
What are the metric and standard units of measurement of temperature?
What are Celsius and Fahrenheit?
Choose 1 of the 4 types of spacecraft that we talked about and tell how it is designed to deal with heat.
Capsule- a material on the bottom that would melt and cool the capsule like human sweat.
Shuttle- silicon quilted blanket and ceramic tiles.
ISS- mylar and dacron blankets and ammonia-filled cooling pipes
Probes- gold paint, aerogel, fluid filled tubes
Glass, brick, air, and plastic are all considered good this, while metals such as aluminum, copper, silver, and iron are considered this.
What are insulators and conductors? (Be sure to know the definition of each)
In what 3 ways can you see conduction, convection, and radiation in a camp fire?
Conduction- the air particles that directly touch the coals are heated.
Convection- as the particles above the fire heat and rise then cool and fall and so forth, we see convection currents.
Radiation- you can feel the heat from the fire several feet away from the fire.
