What is the definition of heat and temperature?

Heat describes the transfer of thermal energy between molecules within a system and is measured in Joules. Temperature describes the average kinetic energy of molecules within a material or system and is measured in Celsius (°C), Kelvin(K), Fahrenheit (°F), or Rankine (R).

What is a simple definition of heat?

Heat is the form of energy that is transferred between systems or objects with different temperatures (flowing from the high-temperature system to the low-temperature system). Also referred to as heat energy or thermal energy.

What is mechanical to heat?

In the history of science, the mechanical equivalent of heat states that motion and heat are mutually interchangeable and that in every case, a given amount of work would generate the same amount of heat, provided the work done is totally converted to heat energy. …

What is heat definition in physics?

heat, energy that is transferred from one body to another as the result of a difference in temperature. If two bodies at different temperatures are brought together, energy is transferred—i.e., heat flows—from the hotter body to the colder.

What is the relationship between temperature and heat?

Explanation: heat is the total energy of the motion of the molecules inside the object or particle, whereas Temperature is merely a measure of this energy. The relationship could be, the more heated an object is there higher the temperature the object will have.

What is mechanical equivalent heat formula?

Mechanical equivalent of heat (J) = Amount of Work (W) / units of Heat (Q). substituting these values we get, Dimensional Formula of Mechanical equivalent of heat (J) = M0L0T-0 . we can also say Mechanical equivalent of heat (J) is dimensionless quantity.

What is heat in science?

What is temperature very short answer?

Temperature is a measure of the average kinetic energy of the particles of a substance. The higher the temperature of an object, the higher is its kinetic energy. Kinetic energy is a type of energy associated with motion.
