12.755 g of a mental initially at 99.0 degrees C are placed into 75.0 g of water initially at 23 degrees C. The final temperature of the water is 24.5 degrees C. Calculate the specific heat of the metal. The specific heat of water is 4.184J/g degrees C

Question

12.755 g of a mental initially at 99.0 degrees C are placed into 75.0 g of water initially at 23 degrees C. The final temperature of the water is 24.5 degrees C. Calculate the specific heat of the metal. The specific heat of water is 4.184J/g degrees C

check_circleAnswer
Step 1

The specific heat can be defined as the amount of heat per unit mass that is needed to raise the temperature of given substance by one degree Celsius.

The specific heat of water is 4.186 joule/gram °C. This can be used to calculate the heat required to raise the temperature for given substance.

Step 2

The relation between heat change and specific heat is shown below;

q Amount of heat supplied
m Mass of the substance
c Substance's specific heat
