How do you distinguish between heat and mechanical effects?
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.
What is definition of mechanical Equivalant in physics?
The mechanical equivalent of heat is a concept in physics that relates mechanical energy to heat energy. It states that a certain amount of mechanical work can be converted into an equivalent amount of heat energy. This concept is quantified by the Joule's constant, which describes the conversion factor between work and heat.
What is dimensional formula of joule's mechanical equivalent?
The dimensional formula of joule's mechanical equivalent is [M][L]^2[T]^-2, where M represents mass, L represents length, and T represents time. This formula expresses the relationship between mechanical work and heat energy.
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.
Friction causes mechanical energy to be transformed into what?
Friction causes mechanical energy to be transformed into heat energy.
What is physical significance of joule's constant?
It is the mechanical equivalent of heat.
What has the author J B Pinkerton written?

How do you convert heat to mechanical?
In some refrigeration systems, mechanical energy is converted to heat energy by mechanically compressing a refrigerant, by means of a compressor; and since refrigerants have a fixed pressure-temperature relationship, much like saturated steam, altering the pressure of a refrigerant correspondingly alters its temperature. I've read of other methods utilizing friction, which is itself mechanical energy in the more pure and direct sense rather than the operation of a mechanical device which itself is utilizing electrical energy, but the compressor example is the only practical real-world application of this nature in common, everyday use that I can think of.

How hot is a joule?
The mechanical equivalent of heat is 4.2 Joules per calorie, so 4.2 Joules can heat 1 gram of water by 1 degree C.

Define what do you mean by mechanical engineering and mention where are the application area of mechanical engineering mention at least in manufacturing and power production?
Mechanical engineering is concerned with the design, construction, and operation of power plants, engines, and machines. It deals mostly with things that move. One common way of dividing mechanical engineering is into heat utilization and machine design. The generation, distribution, and use of heat is applied in boilers, heat engines, air conditioning, and refrigeration. Machine design is concerned with hardware, including that making use of heat processes.

Can heat energy change into mechanical energy?
It will still be heat energy, but it can be converted to mechanical energy
What does the heat does?
