Question

A piece of metal having a mass of 150.0000 grams is heated to 99.3 degrees Celsius. When the hot is submerged in 50.0000 grams of water originally at 21.3 degrees Celsius, the final temperature of the water and metal is 48.4 degrees Celsius. Determine the Specific heat of the metal?

A.) From the mass of the water, the specific heat of the water and the temperature change of the water, calculate the amount of heat in Joules, that was gained by the water. does this heat have a positive sign or a negative sign?

B.) If heat was lost by the metal, what is the sign of the heat change for the metal?

C.) If the amount of heat lost by the metal was the same as the amount of heat gained by the water, what is the value (including sign) of the heat change for the metal?

D.) From the heat change of the metal, the mass of the metal, and the temperature change of the metal, determine the specific heat of the metal.

Explanation / Answer

Heat energy = Mass * Specific heat * ? Temperature

The specific heat of water = 1 calorie per gram *
