A copper calorimeter that weighs 300g contains 200g Oil initially at 293.15K. 180g of Aluminium at 300°C is added to the oil. What will be the final temperature of the system after equilibrium is established?
Specific heat capacity for Copper = 0.379J/g°C
Specific heat capacity for Aluminium= 0.921J/g°C
Specific heat capacity for Oil= 1.54 J/g°C
A lead block of mass 2kg falls from a height h to the ground. The specific heat capacity of lead is 120J/kgk and the rise in temperature is 0.4°C. Calculate the height

C and discharges 3000kJ of
heat to a building to maintain it at 20^oc
C. What is the COP of the heat pump? What is the
minimum required cycle network? Please this is the right answer i need the solution. (1.5, 2000kJ)
A 22 kg dog takes advantage of its owner's absence to jump up on the furniture. It sits on a 1.2 meter long coffee table, 0.4 m from the right side. The table top has a mass of 5 kg and each leg is attached 0.1 m from the ends of the table. Find the force from the right and left legs of the coffee table. answer
