Heat effects involve the transfer of thermal energy leading to changes in temperature, while mechanical effects involve the application of forces leading to changes in shape or movement of objects. Heat effects typically result in temperature changes without physical displacement, while mechanical effects involve physical displacement or deformation of objects due to the application of forces.

How do distinguish between heat and mechanical effects?
Heat effects involve transfer of thermal energy leading to changes in temperature, while mechanical effects involve physical forces or movements causing changes in shape or position of objects. Heat effects can lead to expansion or contraction of materials due to thermal energy, while mechanical effects result in physical deformations or displacements caused by applied forces.
What are the practical application Mechanical equivalent of heat?
The Mechanical Equivalent of Heat shows the relationship between mechanical work and heat energy. It has practical applications in the study of thermodynamics and energy conversion processes. For example, it helps in understanding how engines and other mechanical systems can convert heat energy into useful work.
Who gave the relationship between mechanical energy and heat energy?
The relationship between mechanical energy and heat energy was established by James Prescott Joule through his experiments in the mid-19th century. Joule's work demonstrated the principle of conservation of energy and showed that mechanical work could be converted into heat energy.
What type of energy is friction?
Friction converts mechanical energy into heat energy due to the resistance between two surfaces in contact. It is a dissipative form of energy that results in the loss of mechanical energy during motion.
Mechanical energy is converted into heat energy when?
Mechanical energy is converted into heat energy when friction is present during the movement of objects. Friction between surfaces creates resistance, causing the mechanical energy to be transformed into heat due to the movement of particles and the generation of thermal energy.

Main difference between VA and W?
VA and W both are units of power. VA indicates the power is of an electrical nature. W does not distinguish whether the energy source is electrical, mechanical, magnetic, heat or otherwise.
What studies the relation between heat and mechanical work?
thermodynamics

What are examples for mechanical heat energy?
Examples of mechanical heat energy include frictional heating produced when rubbing hands together, the heat generated when braking a car, and the heat generated from compressing air in a bicycle pump.
Can heat energy change into mechanical energy?
It will still be heat energy, but it can be converted to mechanical energy
How does mechanical energy change into heat energy?
Mechanical energy can change into heat energy through friction. When two objects rub against each other, the mechanical energy of their motion is converted into heat energy due to the resistance between their surfaces. This process results in the generation of heat and an increase in the overall temperature of the system.
