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.
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.
yes,according to relation coefficient of linear expansion depends upon original length.
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
evaporation
The property is flammability.
The solubility of silver chloride increases five fold upon heating to 100°C.
Depending upon your location and the amount of heating oil you have your local heating oil distibutor may buy back your unused heating oil, if for example you are switching to gas. If you are moving house it would probably be easier to see if the new owner will purchase the oil from you.
