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)?
T(K) = θ(°C) + 273
T(K) = θ(°C) - 273
θ(°C) = T(K) + 273
θ(°C) = T(K) - 273
|
What is the Kelvin temperature equal to 40°C?
308 K
283 K
318 K
313 K
|
What happens to the internal energy of a substance as its temperature increases?
it increases
it fluctuates randomly
it decreases
it remains constant
|
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 decreases
it remains the same
it becomes zero
it increases
|
When two objects stop exchanging heat energy, what can be said about their final temperatures?
they must be the same
they must be different
more information is needed
no relationship exists
|
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?
A and B are in thermal equilibrium
A and B must have different temperatures
no conclusions can be made
more information is needed
|
What happens when two objects at different temperatures are brought into thermal contact?
the hotter object becomes hotter
heat flows from higher temperature to lower temperature
the temperatures remain unchanged
|
What happens to particle motion as temperature decreases towards absolute zero?
particle motion remains unchanged
particle motion ceases completely
particle motion decreases
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.
