ICE IS THE BEST EXAMPLE

Strictly speaking, a chemical change occurs when the bonds between atoms are either made or broken (often both).  Bonds can be either covalent (electrons are shared), ionic (one or more electrons are given up by one or more atoms and given to another atom or atoms), or metallic.  Burning something is a chemical reaction.

Depends on the temperature. At a guess at melting point not that different from solid aluminum.

Lowering down the temperature can delay the melting of ice or you can add another substance like common salt to it.

answer can be a or c, but i'd go with answer c.\n\nthe melting point (which solid becomes liquid) varies by each molecules & substances.  What happen is when temp. rises, it translates into more energy put into the soild or heat absored by the solid.\n\nHowever, you can melt solid by chaning pressure, and leaving temp constant.\n\nSo best answer would be C, by heat absorption.

Depending on it's composition, it can have a melting point of about 1400-1600 °C. However, there are glasses that will melt at lower temperatures but those are not common among commercial nor industrial usage.

The other name for a chemical change is a permanent change.This is because once a chemical change has taken place we cannot obtain the reactants back from the products formed during this change.\nexample=burning of wood to produce ash.We cannot get back the original wood from the ash that has been formed during this change.

The temperature where the substance turns from a solid to a liquid. The melting temperature of ice is 31.9999 degrees Fahrenheit.\n\nThe melting point for gold would be much higher as it must be very hot for gold to turn to a liquid.

It does completely. High melting points arise when the atoms of a substance interact and form strong inter-molecular bonds. These are weaker than ionic bonds and covalent bonds but work on the same principle. If the distance between the two atoms is great, the bond strength is low and vice versa. Thus, since potassium has a larger atomic radius, the inter-molecular bonds are weak and it is easier to melt a sample of potassium.

All matters dosnet expand on heat. Take ice, it shrinks or melts on heat. Hope you liked my short and sweet answwer.

a chemical change changes the structure of a substance and a physical change doesn't.\n  chemical change:\n  when the gas leaves the water H2CO3= H2O + CO2\n  melting of a metal\n  physical changes:\n  boiling water\n  cutting a piece of metal in half

Any phase change wil change the texture.  Boiling or freezing, suplimation or evaporation...\nAs for the mass, I don't see.  Unless you throw away some...
