Unknown SPecific Heat Capacity

In summary, to find the specific heat capacity of an unknown material, a 50g piece is heated to 80 degrees Celsius and fully immersed in a well-insulated calorimeter filled with 100g of water at 10 degrees Celsius. This results in a 5 degree increase in the temperature of the water. The heat capacity of the calorimeter is 20 J K-1. Using the equation Q=mc∆T, the final temperature of the unknown substance can be calculated.

Homework Statement


In order to find the specific heat capacity of an unknown material,
a 50g piece is heated to 80 degrees Celsius and fully immersed in a well
insulatyed calorimeter filled with 100g of water at 10 degrees Celsius raising the temperature of the water by 5 degrees, the heat capacity of the calorimeter is 20 J K-1


Homework Equations


MC delta T = MC delta T ?




The Attempt at a Solution


no idea to be honest
at first i thought i can just use Q=mc delta T to do this but i don't know what Q is :S

The final temperature of substance is same as that of water. You could still use the eqn. you wrote.
 

Related to Unknown SPecific Heat Capacity

1. What is specific heat capacity?

Specific heat capacity is the amount of heat required to raise the temperature of one gram of a substance by one degree Celsius. It is often represented by the symbol "C" and is measured in joules per gram per degree Celsius (J/g°C).

2. Why is specific heat capacity important?

Specific heat capacity is important because it helps us understand how much energy is needed to change the temperature of a substance. This information is useful in many fields, including chemistry, physics, and engineering.

3. How is specific heat capacity determined?

Specific heat capacity can be determined experimentally by measuring the change in temperature of a substance when a known amount of heat is added to it. It can also be calculated by using the mass, temperature change, and amount of heat transferred.

4. What factors affect specific heat capacity?

The specific heat capacity of a substance is affected by its chemical composition, temperature, and phase (solid, liquid, or gas). It can also vary depending on the pressure and presence of impurities.

5. Why is the specific heat capacity of some substances higher than others?

Substances with higher specific heat capacities require more energy to change their temperature compared to substances with lower specific heat capacities. This is because these substances have a higher heat capacity, meaning they can absorb more heat energy before their temperature increases significantly.
