Heating a substance usually makes it expand
Heating a substance can make it change state (solid to liquid, liquid to gas, gas to plasma)
Heating a substance can make it emit light at shorter wavelengths
Heating a substance can make it more malleable.
Heat operations caused change in the form physical connection between steel atoms.
Producing heat is usually a physical change because it does not involve the formation of new substances. Heat is often a result of changes in energy levels or motion of particles in a system, rather than a chemical reaction that creates entirely new molecules.
The physical effect of fat to the human body is to slow down the heat loss or accelerate the heat loss relative to the surrounding in order to maintain a body temperature of 370 centigrade. Also it provides cushion effect with less Impulse which is equal to mass x acceleration and of course a well fed look with roundish contour sometimes adding to the curves and beauty.
how does physical environment effect human sediment?
The heat conductivity of a substance does not involve changes to its chemistry. Heat conductivity is a physical change and characteristic to a substance.
Heat capacity is a physical property.
Of course. Heat , cold, lack of oxygen, dust in the air, chemicals ALL contribute to one's health.
heat stroke, heat cramps and heat exhaustion
Heat and temperature are not the same physical quantity. Heat is the cause and temperature is the effect. Heat is measured in joule and temperature in kelvin. Q = m s @ Q - the quantity of heat, @ is the temperature difference. They are proportional. So expecting both to be the same is almost meaning less. If suppose 'm*s' happens to be 1, then Q and @ will be having the same numerical value. Yet they are different physical quantities.
heat effect
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
Heating a bar magnet is a physical change because the magnet does not undergo a chemical reaction. The heat energy causes the atoms in the magnet to vibrate, which disrupts the alignment of the magnetic domains within the magnet, thereby reducing its magnetic strength.
