Is 2 degrees Celsius cold?

A block of aluminum with a mass of 2.6 kg is at 13 degrees Celsius?

• A block of aluminum with a mass of 2.6 kg is at 13 degrees Celsius and comes in contact with a hot block of copper with a mass of 10.2 kg at 93 degrees Celsius. What is the equilibrium temperature in Celsius degrees? Caluminum = 0.22 kcal/kg degrees Celsius Ccopper = 0.093 kcal/kg degrees Celsius

• Answer:

  let t = equilibrium temperature. heat gained by aluminum = heat lost by copper 2.6 x 0.22 x (t-13) = 10.2 x 0.093 x (93-t)...................solve for t
