A block of ice has little thermal energy. If you place it in a warm room, it melts into warm liquid water, which has much more e
Naily [24]

<u>Answer:</u>

<em>The energy to turn the ice into water:</em>

  • The energy that is required to change the state of ice into a liquid is obtained in the form of heat energy from the ambient temperature of the warm room.
  • Once this heat energy is absorbed, the individual molecules of ice gain kinetic energy and start vibrating faster.
  • Yet, the temperature of the ice remains constant until the ice reaches its melting point because this energy is first utilised to break all the bonds of the lattice structure of the ice.
  • After all the bonds are broken and all of the ice has changed into water, if more heat is provided again, then the temperature of the water will increase.

How can you determine the specific heat of a metal using a calorimeter
zhannawk [14.2K]

Answer:

One can determine the specific heat of the metal through using the clarimeter, water, thermometer and using heat equations.

Explanation:

You can learn about heat effects and calorimetery through a simple experiment by boiling water and heating up the metal in it. Then, pour it into your calorimeter and the heat will flow from the metal to the water. The two equlibria will meet: the metal will loose heat into its surroundings (the water) and teh water will absorb the heat. The heat flow for the water is the same as it is for the metal, the only difference being is the negative sign indicating the loss of the heat of the metal.

In terms of theromdynamics, we can deteremine the heat flow for the metal becasue it would be equal to the mangnitued but opposite in direction. Thus, we can say that the specific heat of water qH2O = -qmetal.
