When you transferred the hot metal from the boiling water and into the calorimeter (coffee cup), if the thermometer touched the
sergey [27]

When you transferred the hot metal from the boiling water and into the calorimeter,  The effect will be

  • Change in temp is positive
  • Temp of metal V, dT=-ve
  • No change occurs in the specific heat of metal

This is further explained below.

<h3>What is the Specific heat of the metal?</h3>

a )Since the metal of the cup is hot and the water inside is cold, the water's temperature will rise as heat is transferred from the metal to the liquid.

Change in temp is positive

b)

Due to (a), heat is lost from the food to the water in the cup, lowering the metal's temperature.

Temp of metal V, dT=-ve

c)

No change occurs in the specific heat of metal because of its constant property.
