In summary, a kalorimeter is a device used to measure the heat released or absorbed during a chemical reaction or physical process. It works by isolating the reaction or process and measuring the temperature change of the surrounding liquid. It is important to use hot metal in a kalorimeter for industries such as metallurgy and materials science. The heat released by hot metal is measured by recording the temperature change of the liquid. Kalorimeters are commonly used in industries such as metallurgy and materials science, and safety precautions should be taken when handling hot metal in a kalorimeter.

Homework Statement


A copper vessel of 100 gr contains water, 150 gr, and 8 gr of ice. a 100 gr piece of lead at 2000C is thrown in. what's the final temp'

Homework Equations


Specific heat copper: 0.093
Specific heat lead: 0.031
Melting heat water: 79.7[cal/gr]

The Attempt at a Solution


On the left is the calorie change in the lead:
##100\cdot 0.031(200-T)=(158+100\cdot 0.093)T+8\cdot 79.7##
T comes out small and negative

I solved, it doesn't melt the whole ice, i cannot delete the thread, i don't know how to do it
 

Related to Final Temperature of Hot Metal in a Calorimeter

1. What is a kalorimeter and how does it work?

A kalorimeter is a device used to measure the heat released or absorbed during a chemical reaction or physical process. It works by isolating the reaction or process in a closed container and measuring the temperature change of the surrounding water or other liquid.

2. Why is it important to use hot metal in a kalorimeter?

Using hot metal in a kalorimeter allows for the measurement of the heat released during a chemical reaction or process involving metals. This is important in industries such as metallurgy and materials science, where understanding the heat released by metal reactions is crucial for designing and optimizing processes.

3. How is the heat released by hot metal measured in a kalorimeter?

The heat released by hot metal in a kalorimeter is measured by recording the temperature change of the surrounding water or liquid. This change in temperature, along with the mass of the metal and the specific heat capacity of the liquid, can be used to calculate the amount of heat released.

4. What are some common uses for a kalorimeter in relation to hot metal?

Kalorimeters are commonly used in industries such as metallurgy, materials science, and manufacturing to measure the heat released during metal reactions. They are also used in research and development to study the properties and behavior of different metal alloys and compounds.

5. Are there any safety precautions to take when using hot metal in a kalorimeter?

Yes, it is important to handle hot metal with caution and use proper protective equipment such as gloves and goggles. The metal should also be cooled to a safe temperature before handling or disposing of it. Additionally, make sure to follow all safety guidelines and protocols when using a kalorimeter to prevent any accidents or injuries.
