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.
Stone does expand upon heating, but the extent of its expansion can be relatively small compared to other materials. The crystalline structure of stone, primarily composed of minerals like quartz and feldspar, has strong bonds that resist significant thermal expansion. Additionally, the specific heat capacity and thermal conductivity of stone can affect how it responds to temperature changes, leading to minimal visible expansion. However, prolonged heating can still cause stress and potential cracking due to differential expansion within the stone.
The relationship is a matter of cause and effect. An independent variable is given as one upon which another variable depends. So, for example, if you heat a metal pipe, the pipe expands. The amount of expansion is dependent upon the amount of heating that occurs, so expansion is the dependent variable, and the heating, which you may or may not control, is the independent variable. All it means is that if the independent variable ungoes a change, there is an associated and predictable change in the dependent variable. The two are linked inextricably, but one is cause, the other is effect, or to put it another way, you control the change in the dependent variable with input into the independent variable, but it doesn't normally work the other way around.
explain why the iodine test gave such results upon prolonged heating
The change of ice to a liquid is melting; the direct change of ice to a gas is sublimation.
yes,according to relation coefficient of linear expansion depends upon original length.
Yes
evaporation
The property is flammability.
The solubility of silver chloride increases five fold upon heating to 100°C.
