Terms
Define Particles
Possible Answer:
A small portion of matter
a particle is a small portion of ______
Matter/any substance
Defiine a periodic table
a table of chemical elements
Kinetic energy is energy __ ______
In motion
Give an example of heat transfer
Basically anything giving off heat to another
Define Weather
Possible Answer:
Weather: How it is going to feel outside on a day to day-to-day basis. Ex: temperature, precipitation
True or False
Particles can be seen by a microscope
False!
Name a gas on the periodic table
hydrogen, nitrogen, oxygen, fluorine, chlorine, helium, neon, argon, krypton, xenon, and radon are gases at standard temperature
give an example of kinetic energy
Basically anything that moves
Define Conduction
Possible Answer:
Conduction: Heat transfer by contact
Define Compression and Expansion
Possible Answer:
Compression: Reducing in volume or making smaller
Expansion: Something becoming larger
What states of matter can you compress?
Gas and Liquid
What is CO2
Carbon Dioxide
True or False
Particles change speed when there is more kinetic energy.
True!
Imagine it's a sunny day, what type of heat transfer is the sun giving off.
Radiation
Explain the two types of energy
Kinetic Energy: Energy in motion
Potential Energy: Energy with potential to move
Are water particles bonded together?
Yes
How many particles are there in H2O
3
Why does a liquid expand when it has more kinetic energy?
Possible Answer:
It expands because with kinetic energy it moves faster which makes the particles wiggle a bit, requiring more room.
What is the type of heat transfer done by mixing fluids.
Convection
Define Convection
Possible Answer:
Heat by mixing fluids (gas or liquid)
Explain Intermolecular Distance and give an example of how different states of matter has a different amount of it
It is the distance between atoms
Possible Example:
An example could be how gas can be compressed the most since it has the most distance unlike solids.
What is CO:
A) Carbon dioxide
B) Copper
C) Carbon and Oxygen
D) Another symbol for Co
E) Copper and Chlorine
C) Carbon and Oxygen
What are all the effects of kinetic energy we learned to particles?
1) The more, the faster
2) The less, the slower
3) The more, the more room particles take up
4) The less, the less room particles take up
Or
1) It changes speed
2) Changes the room it takes up
Name 3 forms of heat transfer
Conduction, Convection, and Radiation
