How would the size of an object affect the rate of change in temperature?
When a substance is heated, its particles begin moving and become active thus maintaining a greater average separation. Materials which contract with increasing temperature are rare; this effect is limited in size, and only occurs within limited temperature ranges. The degree of expansion divided by the change in temperature is called the material's coefficient of thermal expansion and generally varies with temperature.
What does change when the state of matter changes?
Matter changing state is usually a result of the material changing temperature and/or a change in the surrounded pressure on the material. The change of state is usually associated with a change in its density.
Does resistivity depend on length and area of the cross section of the material?
No. Resistivity is a material constant, defined for a standard size of material. For another size of material, it can be calculated. Resistivity is the same for any piece of material; resistance can change.
Materials with a high specific heat can absorb a lot of energy and show little change in temperature?
Yes. Specific heat capacity is the amount of heat energy required to change the temperature of the material, so a material with high specific heat needs a lot of heat energy for its temperature to go up.
Can a material gain energy and not change temperature?
Yes quite possible. This occurs at the change of state. As water gets changed into steam heat will be supplied but the temperature would remain at the boiling temperature.

Why does phase change occur in materials?
Changing the temperature or pressure of a material we can change the phase.
What causes sediment to change in size and shape?

What evidences a physical change?
"A physical change occurs when some of the properties of a material change, but the substances in the material remain the same." "...any actions that change the size and shape of a material, but not its composition." if the shape/form is changed but not its makeup, then that change is physical
What is the temperature at which a substance change from a solid into a liquid?
This temperature is called melting point and is different for each substance or material.

What happens to material when heated do they expand contract change color double the size?
Most materials expand when heated. A few contract under certain circumstances, for instance water contracts when heated between 1 and 4 degrees C. Some change colour, e.g. zinc oxide. Whether they could double in size depends on the material and the temperature increase.
When the temperature rises how does the number and size of the bubbles change?
