Q=mC(Tf-Ti)
C= Q/m/(Tf-Ti) = 11.5/10/3 = .383 kJ/(kg*K)
find out what substance has that heat capacity value:
copper is one of them

When silver coins are found in ancient shipwreck's they are coated with a black crust What question could you decide whether the silver underwent a chemical or physical change?
You would need to know if the silver underwent change that left the silver as it was originally, (in this case, having a black substance attach to it) or a change that made the silver into a new substance (like tarnishing). If the silver is still the same before and after the change, it was a physical change. If the substance is changed into a different substance after the change, it is a chemical change.
Temperature a substance will change from liquid to gas?
Yes, only if the temperature of a substance is increased.
When a substance is undergoing a chance of state the temperature of the substance does not change until the?
change is complete
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
temperature
A substance change from a solid to a liquid at its?
A substance change from a solid to a liquid at its boiling point. This is when it reaches a certain temperature.

What causes a substance to change a phase?
change in temperature
When a substance is undergoing a chance of state the temperature of the substance does not change until the?
change is complete
What is the temperature at which a substance change from a solid into a liquid?
This temperature is called melting point and is different for each substance or material.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
temperature
What is the effect of temperature change to the amount of heat content of the substance?
The effect of temperature change to the amount of heat content of the substance is called heat transfer. As heat increases, the temperature decreases.
