A hot chunk of metal at 120 degrees Celsius is put into water at 20 degrees Celsius. What will happen to the temperatures of the materials?

A. metal and water will both end up at 140 °C
B. metal and water will both end up at 60 °C
C. metal temperature will decrease to 20 °C
D. water temperature will increase to 120 °C

i believe the answer is B: both wind up at 60°C

but it's also reasonable to assume, given enough time, they wind up at 20°C because the water would heat up to cool the metal then slowly release the heat to the air untill they both reach 20°C

if it were me I'd answer B, apologies if I'm wrong

when [oh-] is 10-5  m, and [h3o+] is 10-9  m, the poh is 5 and ph is 9. again in both cases the sum of ph and poh is 14. however, the hydrogen ion concentration is not always going to be equal to exactly 1 x 10 raised to a negative number. for example, we skipped over the value of 2.0 x 10-7.

because of all the things that happen around the us, many people get into arguments which sadly could get physical, but we should actually make a change for that.
