Fun Facts
Which has more thermal energy: a glacier or a cup of coffee?
Answer: A Glacier
Why: Glacier, due to immense mass/particles, despite low temp.
Question:"Why does a metal doorknob feel colder than a wooden door in winter, even if they're the same temperature
Answer: Metal conducts energy faster
Why: because of their unique atomic structure
Does matter still have thermal energy at absolute zero?
Yes, but minimal
What is the difference between heat and temperature, heat transfer (conduction, convection, radiation), thermal expansion, and calculations involving specific heat capacity, often asking what it is, how it moves, and why certain things happen
Answer:Heat is energy in transit due to temperature differences, while temperature is the measure of average particle kinetic energy
Question: Is "cold" a type of energy, or the absence of heat?
Answer: Cold isn't a type of energy
Why:t's the absence or lower level of heat (thermal energy), representing a decrease in the motion of atoms and molecules, whereas heat is the kinetic energy of particles. Think of it like darkness: darkness isn't a substance but the absence of light; similarly, cold is the absence of heat energy, and cooling something means removing its heat.
Is cold a substance, or the absence of heat?
Absence of heat
is heat the same as thermal energy?
Answer: No
Why:heat is the transfer of thermal energy. Temperature is the measure of how hot or cold something is.
If you have a hot cup of cocoa and a giant hot tub of water at the same temperature, which has more thermal energy
Answer: The giant hot tub of water
Why: Has vastly more thermal energy because thermal energy depends on both temperature and the total mass of the substance.
What are the three ways heat transfers
conduction, convection, radiation
How is a hot pebble different from a cool boulder in terms of thermal energy, even if they have the same temperature?
Answer: A hot pebble and a cool boulder that are at the same temperature do not differ in thermal energy based on their temperature alone.
Are heat and temperature the same?
No, temperature is average kinetic energy, heat is energy transfer
Why is conduction slow in gases
particles far apart
Does all matter have thermal energy
Answer:Yes
Why: Even in deep space, as particles still vibrate.
Does heat transfer from hot to cold or cold to hot?
Hot to cold
what are the 3 main primary states of matte
solid, liquid, gas
