1】 What do you mean by a reversible change ?2】What do you mean by a irreversible change 3】 What are physical change? give 2 examples ? 4】what are chemical change ? give two examples ?5】 Describe an irreversible change that you about by hitting?6】 Describe an reversible change that you about by hitting? 7】Mention 2 change that you can be bought about by applying pressures? |
|
Answer» (1)change which can happen backward, that is, can be reversed is called a reversible change. If you keep water in the freezer for some TIME, it transforms into ice. But as soon as you take it out of the freezer, it turns into water again. This is a reversible change.(2)A reversible change is a change that can be undone or reversed. If you can GET back the substances you started the reaction with, that's a reversible reaction. ... Examples of reversible reactions include dissolving, evaporation, melting and FREEZING.(3)physical change involves a change in physical properties. Examples of physical properties include melting, transition to a gas, change of strength, change of durability, changes to crystal form, textural change, shape, size, color, volume and density.(4)Rotting, burning, cooking, and rusting are all further types of chemical changes because they produce substances that are entirely new chemical compounds. For example, burned wood becomes ash, carbon dioxide, and water.(6)when you burn a paper by heating it vhanges into ash,which cannot be converted back to paper, which is irriversible change.(7). intermolecular force of attraction increases as the particles COME closer to each other on applying pressure. . thermal agitation DECREASES as the particles lose their ability to repel each other. |
