Most likely it's caused by the fact that supplied heat is transferred to external electronic orbits. When provided some energy external electrons will jump to higher levels which are located farther from nuclei then non-exited. The latter one causes effective radius of atom to increase, in its turn electronic levels of neighboring atoms get closer and in order for the system to be in equilibrium the atoms have to move from each other. As result bodies expend while is being heated.
heat is removed in freezing .
Heat does not affect it. It expands with coolness. It contracts with heat.
If 2500 cal. of heat were supplied to 10g of iron at 10c what is the final temperature of iron?
Body heat is a form of thermal energy produced by metabolic processes within the human body. It is primarily generated as a byproduct of the body's internal functions, such as digesting food, breathing, and exercising. This heat helps to regulate body temperature and maintain overall physiological function.
heat strain or the thermal strain is caused due to the temperature changes. A solid body expands as the temperature increases and contracts as the temperature decreases.this causes the thermal strain. for a homogeneous and isotropic body the thermal strain is caused by change in temperature. thermal strain = coefficient of linear thermal expansion * change in temperature where the coefficient of linear thermal expansion gives the strain per degree of temperature.
Spaghetti is originally hard and contracted. When heat is supplied to any object, most of them expand. so, when heat is supplied to spaghetti, it expands. However, it is important to note that expansion due to increase in temperature (Thermal expansion) is a very small. So, spaghetti expands only by about an inch.
Well, solids. For example, when you heat up metal is expands and when you freeze it, it contracts

Yes, wood expands when exposed to heat.
Yes about 1 inch. That's because the spaghetti originally is contracted and hard. And heating normally expands a substance, so when the spaghetti is boiled, the heat supplied causes it to expand a little.
it melts
when solid has already melted and when heat is supplied it starts increasing the temperature of liquid
when the temperature of the body is lowered or raised, it contracts or expands accordingly. If this expansion or contraction is prevented, then a stress is produced called thermal stress
Th water on your body evaporates into the air and since evaporation ... You can experience temperature change due to compression by examining a can of ... your body it feels very cold because the compressed gas expands and loses heat.
This cannot be answered. This does not make any sense.
pretty much everything.....depends on the heat
