Which One of the Following Situations Is a Direct Application

question 19

Multiple Choice

Which one of the following situations is a direct application of the Zeroth Law of Thermodynamics?

• A)Block A has twice the temperature of block B before they are brought into contact.Upon contact,heat flows from block A to block B.
• B)A sample of gas within a cylinder with a piston is held at constant temperature and pressure while it is allowed to expand.During this process,the gas absorbs heat from its surroundings.
• C)The motor of a refrigerator uses electric energy to remove heat from inside the refrigerator and transfer it to the room.
• D)A physicist removes energy from a system in her laboratory until it reaches a temperature of 3 × 10^-¹⁰ K,a temperature very close to (but still greater than)absolute zero.
• E)A thermometer is calibrated by placing it in an ice water bath within an adiabatic container until the thermometer is in thermal equilibrium with the ice water.

Definitions:

Measurement Error

The difference between the observed value and the true value of a variable, due to inaccuracies in data collection or analysis.

Alternate Forms Reliability

A measure of reliability used to assess the consistency of the results of two tests constructed in the same way from the same content domain.

Scores Consistency

The degree to which test scores for an individual or group remain stable over repeated applications of the same measurement.

Time Sampling Error

A statistical error that occurs when a sample is collected at a specific time that is not representative of the overall population or phenomenon.
