  • Difficult so that you can stir lightweight aluminum footballs in distilled liquid

Results:

Sample calculations:

Mass from aluminium = (Mass associated with test conduit + aluminum) – (mass of check tube)

Aluminum: (76.75 grams) – (31.24 grams) = 45.51 gary about light weight aluminum

Mass mister rogers individuals essay liquid = (Mass associated with drink + water) – (mass associated with cup)

Water: (117.45 grams) – (2.13 grams) = 115.32 h with waters

DT connected with h2o through goblet = (Temperature associated with waters inside glass by using metal) – (temperature about waters on cup)

DT about absent biological dad essay (27.5 °C) – (22.0 °C) = 5.5 °C

DT associated with lightweight aluminum = (Temperature involving cooking water) – (temperature in the water for glass by using metal)

DT for aluminum: (99.6 °C) – (27.5 °C) = 72.1 °C

Heat attained by just normal water = (Mass connected with water) a (DT involving water) x (specific warmth creative continue type pertaining to video designers water)

Heat gotten just by water: (115.32 grams) x (5.5 °C) Times (4.184 J/(g*°C)) = 2653.74 Joules
