This quiz contains 14 questions from a mix of 1 subtopics.
What temperature scale has its zero point at absolute zero?
rankine
fahrenheit
kelvin
celsius
|
What is the conversion formula between Celsius (°C) and Kelvin (K)?
θ(°C) = T(K) - 273
T(K) = θ(°C) + 273
θ(°C) = T(K) + 273
T(K) = θ(°C) - 273
|
What is the Kelvin temperature equal to 40°C?
313 K
308 K
318 K
283 K
|
What happens to the internal energy of a substance as its temperature increases?
it remains constant
it fluctuates randomly
it decreases
it increases
|
What causes an increase in the internal energy of a substance?
increased potential energy between particles
both of the above
increased kinetic energy of particles
|
What typically happens to kinetic energy during a change of state?
it remains the same
it becomes zero
it decreases
it increases
|
When two objects stop exchanging heat energy, what can be said about their final temperatures?
they must be different
no relationship exists
more information is needed
they must be the same
|
According to the zeroth law of thermodynamics, if A and C are in thermal equilibrium, and B and C are in thermal equilibrium, what can be concluded?
no conclusions can be made
A and B are in thermal equilibrium
A and B must have different temperatures
more information is needed
|
What happens when two objects at different temperatures are brought into thermal contact?
the temperatures remain unchanged
the hotter object becomes hotter
heat flows from higher temperature to lower temperature
|
What happens to particle motion as temperature decreases towards absolute zero?
particle motion remains unchanged
particle motion decreases
particle motion ceases completely
particle motion increases
|
What is the term used to describe the total kinetic and potential energy of the particles in a system?
|
What do we call the temperature point where molecular motion stops?
|
Define thermal equilibrium in your own words.
|
Explain why increasing the temperature of a substance leads to an increase in internal energy.
