Animals make use of chemical reaction to convert the food they eat to energy
Leaves of plants use chemical reaction through photosynthesis, changing carbon dioxide and water to glucose and sugar. Ripening of fruits also requires chemical change
Too much freezing and melting deforms plastic wares and other household materials.
Too much evaporation results in too much withering of plants and soil
Too much condensation of water leads to too much precipitation, which can cause landslides and flooding
Physical Change: Good Side
Physical Change: Bad Side
1. Freezing enables us to store and preserve meats and other foods in a long period of time. Microorganisms, the ones that cause food spoilage, hate cold places.
2. Melting is used in metal industries to mold cans, furniture, utensils, and swords. Some of the toys are also molded by melting.
Environmental Changes
Physical Change: Good Side
3. Evaporation is a crucial part of the water cycle. Water from all areas on Earth will not be recycled if they will not evaporate and turn into water vapor as clouds in the sky.
4. Condensation is important in transforming water vapor to droplets water stored in clouds.
1. Ozone Depletion - The ozone layer is now reduced significantly due to chemical change.
2. Global Warming - The greenhouse gases, such as carbon dioxide and carbon monoxide, are naturally found in the atmosphere. But when there is too much build up of carbon dioxide and carbon monoxide, the heat generated by the planet Earth is trapped that cause global warming.
3. Acid Rain - is a rainwater - made acid pollution that can cause harm to our environment.
