Temperature is distinguished from heat when we note that whereas temperature is ____________________. A) None of these.B) measured in degrees, heat is measured in units of energy.C) a measure of average translational kinetic energy per molecule, heat is energy that moves from high to low temperature.D) All of these.E) a ratio of energy/molecule, heat is energy in transit.
The correct answer is D) All of these.
Temperature is a measure of average translational kinetic energy per molecule. It is typically measured in degrees. Heat, on the other hand, is a form of energy that flows from a higher temperature region to a lower temperature region. It is measured in units of energy.
To understand this concept, you can think of temperature as the intensity or level of molecular motion, and heat as the actual transfer of energy due to a temperature difference. It's important to note that temperature and heat are related but distinct properties.
To arrive at the correct answer, you can analyze the given options:
A) None of these - This is incorrect, as all of the options need to be considered.
B) Measured in degrees, heat is measured in units of energy - This is partially correct, as temperature is indeed measured in degrees and heat is measured in units of energy. However, there are additional aspects to consider.
C) A measure of average translational kinetic energy per molecule, heat is energy that moves from high to low temperature - This statement is correct. Temperature is indeed a measure of average translational kinetic energy per molecule, and heat flows from regions of high temperature to low temperature.
E) A ratio of energy/molecule, heat is energy in transit - This is also correct. Temperature can be thought of as a ratio of energy per molecule (kinetic energy) and heat is energy in transit from one object to another.
Thus, the correct answer is D) All of these, as all the statements given in the options are true regarding the distinction between temperature and heat.
