A 50 g piece of aluminum metal with an initial temperature of 120 °C is dropped into 100 g of water, with an initial temperature of 20 °C, in a perfectly insulated calorimeter. The final temperature of the metal and water is 44.41 °C. What is the specific heat capacity (c) of aluminum?
c=q/mΔT
Solve with above equation (i really need to know the steps for this question as i don't have to answer with these numbers but with other numbers i just need to understand how to do it.Thank you)
