Physics
Specific Heat of Metal and Water
Purpose: To determine which essence has higher incite capacity; wet or metal.
Background Information:
1)Temperature: Quantity that tells how importunate or cold something is compared to a standard.
2)Heat: brawn that transfers from star purpose to another because temperature difference. It is energy in transit from a carcass of higher temperature to one of lower temperature.
3)Mass: measure of an objects inertia or the amount of matter in an object.
4)Specific passionateness is the amount of hotness needed by 1 gram of a substance so that it changes by 1 degree Celsius.
5)Specific heat ? Energy ? Ek (kinetic)
? Ep (potential)
Materials: 2 beakers, hot plate or 2 kindred lab burners, 2 thermometers, 1 piece of look at, balance.
Hypothesis: I mobilise that the metal will have a higher heat capacity because metal uses almost all the energy (heat) to adjoin its particles kinetic energy while water tends to store its energy.
Procedure:
1)Determine the book of the two beakers.
2)Determine the mass of the lead and place it in one beaker with an egual mass of water.
3)Add water to the beaker couple to the mass of water and lead in the first beaker.
4)Place the two beakers on the hot plate or over the two burners so that the beakers are receiving equal amounts of heat.
5)Observe and record what the change in temperature every 15 seconds.
Data:
1st beaker: 222.4 grams
2nd beaker225.7 grams
Lead: 31 grams
1st Beaker + water: 253.4 grams
1st Beaker + water + lead: 284.4 grams
Water + lead: 62 grams
2nd beaker + water: 287.7 grams
