Measuring the change in temperature versus time upon addition of a hot metal specimen to 10.02 ml of water with an initial temperature of 26.63 degrees C led to a plot with a line with the equation y= -0.121 x + 36.2. If the heat absorbed by the water is equal to the heat lost by the metal, determine the specific heat of the metal with a mass of 10.69g to two decimal places.
Please explain how to solve this.

The specific heat of a certain metal can be determined by measuring the temperature change that occurs when a piece of the metal is heated and then placed in an insulated container that is made of the same material and contains water. Suppose the piece of metal has a mass of 95 g and is initially at 100°C. The container has a mass of 190 g and contains 462 g of water at an initial temperature of 20.0°C. The final...

Please help how to solve this question An unknown metal weighting 13.11 g at a temperature of 81.0 degrees Celius is place in a calorimeter containing 25.0 mL of water at a temperature of 25.0 degrees Celsius. The final equilibrium temperature is 30.0 degrees Celius. What s the specific heat of the metal? The specific heat of water is 4.184 J/g-C. Assume the density of water is 1.00g/mL and that there is no heat lost or gained by the calorimeter.
