Answers
Answer:
1. As temperatures increase, additional heat energy is applied to the constituent parts of a solid, which causes additional molecular motion. Molecules begin to push against one another and the overall volume of a substance increases. At this point, the matter has entered the liquid state.
2. For example, adding thermal energy — heat — to liquid water causes it to become steam or vapor — a gas. Taking away energy also causes physical change, such as when liquid water becomes ice — a solid — when heat is removed. Adding energy to matter causes a physical change — matter moves from one state to another.
3. In a solid, molecules are packed together, and it keeps its shape. Liquids take the shape of the container. Gases spread out to fill the container. Solid is one of the three main states of matter, along with liquid and gas.
4. the melting point is the temperature at which a material changes from a solid to a liquid (melts). Keep in mind that a material's melting point is the same as its freezing point. The melting point of ice is 273.6 degree Kelvin. ... To convert K to °C, subtract 273.15.
5. Latent heat is a form of internal or potential energy stored by evaporated or melted water. ... A total of 334 J of energy are required to melt 1 g of ice at 0°C, which is called the latent heat of melting. At 0°C, liquid water has 334 J g−1more energy than ice at the same temperature.
hope this helps :)
