physical change
The expansion of matter upon heating is an example of a thermal expansion, which is the tendency of matter to change in volume, area, and length in response to a change in temperature.
physical change
The expansion of matter upon heating is an example of a physical change. This is because the substance undergoes a change in form or appearance without forming a new substance.
For example heating lead to melting and boiling - changes of matter phases.
Yes, energy can cause a change in matter through processes like heating, cooling, or reacting with other substances. For example, heating water causes it to evaporate into steam, which is a change in its physical state due to the addition of heat energy.
By heating or freezing.
Thermal expansion is the tendency of matter to change in volume in response to a change in temperature.
By heating or freezing.
Cooling or Heating First of all we have 3 phases, Gas, Liquid and Solid to change from gas to liquid to solid, cooling is required and to change from solid to liquid to gas, heating is required This type of heat is called latent heat, always think of water as an example Ice --> Water , heating Water--> Water Vapour, more heating
Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.
Expansion is a physical change because it involves a change in the state or size of matter without altering its chemical composition.
Thermostats are devices that operate based on the expansion of matter as temperature increases. This principle is used to control heating and cooling systems by sensing changes in temperature and activating the appropriate response to regulate the temperature in a space.
