Question

A piece of iron (Cp = 0.450 J/(gi°C)) has a mass of 60.0 g. It is submerged in 125 g of water (Cp = 4.184 J/(gi°C)) at 30.0°C. The temperature of the system (iron and water) changes to 33.2°C. What is the temperature change of the iron?

~ 3.2°C
~ 51.1°C
~ 62.0°C
~ 65.0°C

(I think it's the first answer but I'm not sure.)

Answer 1

if the temperature starts at 30, and changes to 33.2, what's the overall change?

Answer 2

3.2 degrees

Answer 3

it is

Answer 4

but I wasn't sure if there was another step.

Answer 5

there usually is another step, that calculates the energy that's absorbed by the metal, but you need to find the change in temperature first. That's all this question actually asks

Answer 6

Oh okay. I see. Thank you.

Answer 7

Could you help me with one more thing? I just can't tell the difference between the answers.

Answer 8

What's the difference between "forming the product" and "product formation"?

Answer 9

You there?

Answer 10

there is no difference, in my opinion

Answer 11

Well, I submitted the assignment and the answer was 62.0°C instead of 3.2°C, but I'm not sure how to get that answer.
Also, I got the answer right on the second question, and it was the third choice.

Answer 12

I'm not sure why these things � keep showing up.

Answer 13

if they're saying the right answer is 62 degrees, then they're wrong or the question is written incorrectly for the answer they want

Answer 14

if the question says "starts at 30 and rises BY 33.2", then the change in temp is 33.2, and the final temp is about 62. No other option would make sense

Answer 15

It is odd. I'll have to ask my teacher about it tomorrow. Thank you for your help though.
