Interpretation:
The quantities temperature and heat are to be compared and contrasted.
Concept introduction:
Temperature: Temperature determines the degree of coldness or hotness in a system.
Heat: Heat is a source of energy which transfers from hot end to cold end.
Answer to Problem 53A
The main difference between heat and temperature is:
Heat involves changes in thermal energy and temperature involves change in kinetic energy.
Explanation of Solution
Temperature is a property of a body but heat is a measure of change in thermal energy.
If a body absorbs heat then its thermal energy increases due to increase in temperature of the molecules and vice-versa.
Heat is expressed in joules where temperature is expressed in degree Celsius, Fahrenheit or Kelvin
Second law of
Heat always flows from hotter body to colder body.
Heat and temperature are related terms. Heat is a variable where temperature is the property.
