What's the Correct Temperature of the Bolt Before Placing in Water?

In summary, a 21.3 g aluminum bolt was heated and placed into a copper calorimeter cup with a mass of 137 g, containing 839 g of water at an initial temperature of 16 oC. The final equilibrium temperature was found to be 18.4 oC. The formula used to calculate the initial temperature of the bolt before it was placed in the water was Tf = (m1C1T1 + m2C2T2) / (m1C1 + m2C2), but the calculated answer of 541.3 degrees Celsius was incorrect. It is worth noting that the formula only accounts for two masses exchanging heat, but in this scenario, there are three masses involved. It

An aluminum bolt has a mass of 21.3 g. It is heated then placed into 839 g of water in a copper calorimeter cup with a mass of 137 g. The initial temperature of the water and the copper cup is 16 oC. The bolt, water and cup arive at an equilibrium temperature of 18.4 oC. What was the temperature in degrees celcius of the bolt before it was placed in the water?

I used this formula and got wrong answer, need help.

Tf = (m1C1T1 + m2C2T2) / (m1C1 + m2C2)

And got 541.3 Degrees C. What is wrong.?

The first thing that pops out to me is that you have three masses exchanging heat, but your equation only accounts for two of them...

Where does this formula come from? and what do the variables mean?
Can you show more work? What did you plugged in for the various variables?

Why is this in the advanced forum?
 

FAQ: What's the Correct Temperature of the Bolt Before Placing in Water?

1. How is intelligence measured?

Intelligence is commonly measured through IQ tests, which assess an individual's cognitive abilities such as problem-solving, memory, and reasoning skills.

2. Can intelligence be improved?

Research suggests that intelligence can be improved through education, environmental factors, and continuous learning and development.

3. Is there a difference between intelligence and knowledge?

Yes, intelligence refers to an individual's ability to acquire and apply knowledge, while knowledge refers to the information and skills that a person has acquired through education and experience.

4. Are there different types of intelligence?

Yes, there are multiple theories of intelligence, and some propose that there are different types of intelligence, such as emotional intelligence, social intelligence, and creative intelligence.

5. Can intelligence be inherited?

While genetics may play a role in intelligence, studies suggest that environmental factors, such as education and upbringing, have a more significant impact on a person's intelligence.
