I need examples of physical changes that occur in daily life?

Breathing- intake of O2 and exhaling CO\nEating- converting foods to sugars to energy

any change from one state (gas, liquid, solid) which is accompanied by alteration of the chemical composition; any process in which one or more substances are changed into one or more different substances

The key here is the wording.  Transformation means change, and the sun's energy always arrives as radiation.  The organization of atoms is also constant - numbers of neutrons and electrons vary, but protons for each atom do not, and each particle stays basically where it should.  Movement indicates a potential for change -- electrons "jump" to your finger from a doorknob or from charged clouds to the ground, as lightning. C

Local phenomena don't really form evidence for global changes.  Despite global warming, the recent winter has been one of the coldest in years for the last fourty years I have experienced.\n\nWeather changes have a much greater amplitude than the small changes caused by global warming. You need to consult statistics to measure those changes, like number and strength of hurricanes in a 10 year interval (to give an example that can be counted rather than tediously measured).

It happens everyday.\nLOL

Physical Changes:\n1.The ice in your glass melts, turning a solid to a liquid\n2. The steak browns on the grill\n3. The potatoes are mashed\n4. The carrots are diced\n\nChemical Changes:\n1. You add lemon to your ice water\n2. You add cream to your coffee\n3. You burn the steak, producing carbon\n4. You clean the sink with baking soda

These are physical changes.  The matter simple changes state, depending on tempature.  Also see evaporation.

Changes in air pressure and possibly humidity.  Your body turns into a barometer.

A rough example as follows:\n\nQuestion: What happens to ICE when you PLACE IT IN WARM WATER?\n\nHypothesis: IT TURNS INTO LIQUID.\n\nMaterials: ICE, CONTAINER, WARM WATER.\n\nSteps: 1.  FILL CONTAINER HALF WAY WITH WARM WATER.\n       2.  PLACE ICE IN CONTAINER.\n\nObservations:  I OBSERVED THE ICE MELT.  THE ICE TRANSFORMED FROM A SOLID TO A LIQUID.\n\nConclusion: ICE A SOLID CAN TRANSFORM INTO WATER A LIQUID WITH THE ASSISTANCE OF INCREASED TEMPERATURE.

Oxygen to carbon dioxide (breathing), food to energy, sleep to rejuvenation, or maybe that last one wasn't so good, try brain activity (thoughts) to actions (automatic brain commands that keep your heart and lungs functioning)

There are temperature changes is most reactions becuase there is heat generated, known as the heat of reaction.

weight changes, stress, birth control, menopause, etc\nthe list goes on and on....can you provide more info?

The differences are that chemical change is when it chemically changes the elements, such as H2O. Physical change is a change where you can physically change substances, such as when you mix salt with water with a spoon. The similarities are that they both combine 2 substances together to create a new compound, I think.       *No guarentee this is correct*

1.Heat is electromagnetic radiation and by using a photocell you could transfer heat into electric energy.\n2.You can also employ a thermocouple to generate some electricity\n3.A steam and Sterling engine can serve as good examples of heat changing into mechanical energy.\n4.Heating and cooling two co-joined metal strips of different linear expansion into buckling and relaxation. \n5.There more examples.
