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 measured in degrees, heat is measured in units of energy.
Temperature is a measure of average translational kinetic energy per molecule, heat is energy that moves from high to low temperature.
Temperature is a ratio of energy per molecule, heat is energy in transit.
The correct answer is D) All of these.
To understand the difference between temperature and heat, let's break down each option:
A) None of these: This is not the correct answer because all the options provided are valid characteristics of temperature and heat.
B) Measured in degrees, heat is measured in units of energy: This is partially correct. Temperature is indeed measured in degrees, while heat is measured in units of energy (such as joules or calories). However, this is not the only distinction between temperature and heat.
C) A measure of average translational kinetic energy per molecule, heat is energy that moves from high to low temperature: This is also partially correct. Temperature is a measure of the average translational kinetic energy per molecule, while heat is, indeed, energy that moves from an object with a higher temperature to an object with a lower temperature. Again, this alone does not fully capture the distinction between temperature and heat.
E) A ratio of energy/molecule, heat is energy in transit: This is another partial explanation. Temperature can be seen as a measure of the average kinetic energy per molecule, and it is not a ratio. Heat, on the other hand, is indeed energy in transit, meaning it refers to the energy transferred between two objects due to their temperature difference.
The correct answer, D) All of these, combines all the correct statements about temperature and heat. Temperature is measured in degrees, it is a measure of the average translational kinetic energy per molecule, and heat is energy that moves from high to low temperature.
So, in summary, while temperature is a measure of the average kinetic energy per molecule, heat refers to the transfer of energy due to temperature difference. Temperature is measured in degrees, and heat is measured in units of energy.
