Thermal Energy

Physics Experiment Thermal Energy order of measuring stick Heat Capacities and precise Heat Capacities 1.

Electrical Method gate: – Finding particularised affectionateness capacities of aluminum, leaf blade, Brass and pig level Aim: – To collect data of the temperature in order to set about the ad hoc lovingness capacities Hypothesis: – The specific shake up capacities of the alloy objects would come out to be: – Aluminium: 897 J kg& damaging;1 K& electronegative;1 – Steel: 420 J kg& negatively charged;1 K−1 – Brass: 380 J kg−1 K−1 – ha ir: 385 J kg−1 K−1 Method: – Let electricity run done a metal object (aluminium, steel, brass, copper) – Record the diversity in temperature of the object afterward 3 minutes – Record the flowing and electric likely different through the object – Use the specific affectionateness capability formula to calculate heat capacity of the from each one object ItV the specific heat capacity c= – m T 2−T 1 unconditional variable: – materials (aluminium, steel, brass, copper) Dependent variable: – temperature (thermometer) – current (ammeter) – potential difference (voltmeter) Control variable: – time – 3 minutes = clxxx seconds – mass – 1 kg Apparatus: – Ammeter – voltmeter – electricity ancestry (8V) – Metal objects (aluminium, steel, brass, copper) – Themometer – stop watch Result: muckle Materials (kg) Copper Steel Brass All uminium Voltage (V) 1 5.54 1 5.55 1 5.55 ! 1 5.5 T1 T2 Current Time (A) (s) (K) (K) 1.81 180 298 three degree centigrade 1.84 180 298 300.5 1.86 180 297 299 1.82 180 297.5 298 Table 1 – work heat capacities ΔT (K) 2 2.5 2 0.5 Specific heat capacity (J kg−1 K−1) 902.47 735.26 929.07 3603.6 shutdown: – The result might be wrong because the purpose is so different to the hypothesis Error, mistake and improvement: – occupation with enter data – read the question...If you want to get a full phase of the moon essay, order it on our website: BestEssayCheap.com
