Thermal Energy and Temperature
What tool do we use to measure temperature and what is one unit we use to measure temperature other than Fahrenheit?
Thermometer; Celsius or Kelvin
Answer 1 of the following questions:
What temperature does water boil at (in both Celsius and Fahrenheit)?
OR
What temperature does water freeze at (in both Celsius and Fahrenheit)?
100 C; 212 F
0 C, 32 F
What is “ . .. the energy transferred between objects that are at different temperatures” (280)
Heat
Define matter, mass, and volume
Matter is anything that has mass and takes up space.
Mass is how much matter something has.
Volume is how much space something takes up.
Fill in the following phrase:
The topich sentence and the clincher sentence must __________ or _______________ 2-3 key words
Repeat; Reflect
True or False increasing kinetic energy and motion of particles increases the thermal energy and temperature of a substance.
True
True or False to get Fahrenheit from celsius you need to use the following formula:
(9/5xC) +32.
True
Give an example of an insulator and a conductor.
Insulator: Glass, fabric, rubber, etc.
Conductor: Metal
How are chemical and physical changes different?
Chemical changes change the identity of a substance and physical changes do not.
Solve the following problem:
10x=2x+2
x=4
How are temperature and thermal energy different?
Temperature is the average speed of particles in a substance, thermal energy is the speed of all of the particles added together.
What do we call the temperature when molecules stop moving?
Absolute 0 or 0 K
True or False. Thermal energy travels from the colder object to the hotter object.
False
Give 1 difference between an element and a compound and 1 difference between an element and a mixture.
Many right answers.
An element is made up of only 1 thing and a compound can contain 2 or more elements chemically combined.
In a mixture the identity of the objects doesn't change (physical change), but in a compound the identity does (chemical change); even though both can be made up of 2 or more substances.
What is the first line in A Christmas Carol by Charles Dickens?
"Marley was dead, to begin with."
True or False. When an object gets cold it is because thermal energy is destroyed.
False.
253 K
How are conduction, convection, and radiation different?
Conduction is when thermal energy transfers between objects that are touching each other.
Convection is when energy transfer occurs between liquid or gases (i.e. fluids).
Convection is when energy transfers through electromagnetic waves.
State 1 of Newton's Laws of Motion
1. An object in motion stays in motion and an object at rest stays at rest unless acted upon by an outside force.
2. Force=mass x acceleration
3. Every action has an equal and opposite reaction.
What major event in Jesus' life did we celebrate on Sunday?
His baptism.
What law tells us that the $400 clue is false?
The Law of Conservation of Energy.
Buttercup's peppermint mocha is 90 C, how many degrees is that in Fahrenheit?
194.
Give an example of conduction, convection, and radiation.
Many right answers:
Conduction: hand on a stove, hand holding a coffee mug, sitting on metal bleachers
Convection: Wind, water currents, magma
Radiation: Sun, microwaves, x-rays, etc.
What 3 particles are atoms made of and what are their charges?
Electrons (negative), protons (positive), and neutrons (no charge/neutral).
Give 1 difference between a federalist and an antifederalist.
Federalist- fine with constitution as in; more power in the federal government
Anti-federalist- want the Bill of Rights added to the constitution- distribution of power more to the states.
