Answer:
Change in temperature formula for a calorimeter,
Q=mC∆T
Aluminium-2.6°C
Steel-1.5°C
Lead pellets-0.6°C
Explanation:
The heat conductivity of aluminum is higher compared with steel.
The initial temperature of water in calorimeter is 30°C.
After heating,the water temperature in calorimeter is 60°C.
