Challenge: Problem 3

We have not answered, or even asked, the question: "what is temperature?" All we have said is that it is measure of thermal intensity. If we want to put some meat around the bare abstract bones of the concept of thermal intensity, we have to invent a model of the internal thermal structure of systems.

A model which provides a picture of thermal intensity is the kinetic model. According to this model, temperature is a measure of the average random kinetic energy of the molecules in the system. Select those items from the RESPONSE ARRAY which belong to the kinetic model, including those items vhich lend support to the notion.

1
temperatures of one empirical scale translated into temperatures of another scale by a formula
2
temperature put directly proportional to pressure of a gas
3
temperature put proportional to measure of thermometric property
4
use of First and Second Laws of Thermodynamics to write an equation for temperature
5
100 degrees specified between the ice point and the steam point
6
number given to the triple point of water: 273.16°K
7
numbers given to fixed points
8
temperature defined so as to increase with increase of internal energy
9
measurements of specific heat under conditions where no work is involved
10
heat input always increases the entropy (thermal extension), and sometimes the temperature (thermal intensity) of a system
11
concept of internal energy as directly proportional to temperature
12
ratio of thermal intensities expressed in terms of quantities of heat and work
13
calibration so as to make thermometer readings as close to the thermodynamic values as possible
14
a system conceived as consisting of myriads of interacting particles
15
measurements of gradient or derivative of temperature with respect to entropy
16
the thermal intensities of two systems cannot be added together
17
an interval of one degree at 200°K does not have the same thermodynamic value as a one degree interval at 400°K
18
reproducible indication of a particular thermal intensity
19
ratio of absolute temperatures
20
a minute part of a system has the same thermal intensity as the whole system
