How many calories are required to raise the temperature of 225 g of water from 42°C to 75 c? A metal object with a mass of 19 g is heated to 96°C and is transferred to a calorimeter containing 75 g of water at 18 °C. The water and metal object reach a final temperature of 22°C. 11. What is the specific heat of this metal object? a. b. What is the metal? ALuuiNuM 12. What mass of chromium metal at 92.0 C would be required to raise the temperature of 250 g of wa 22.0 C to 27.5 C? Assume there is no loss of heat to the environment.Explanation / Answer
Ans 9 :
Specific heat is the amount of heat required by the substance to raise its temperature by 1 celcius per unit mass of it.
When the specific heat is low , less amount of heat will be required to raise the temperature. This means that a lesser amount of heat , will raise the temperature to a greater margin.
Such substances those who have low specific heat , would not be able to retain the higher temperature for longer as slight release of heat will cause their temperature to go down quickly.
