The following questions were asked by visitors named Katherina Ramos.

The amount of heat required to raise 200 g of aluminum by 10 degrees celsius if its specific heat is 0.897 J/gC ? I need help. This is all confusing.

What is the specific heat of a substance if 2100 J is required to raise a 312 g sample by 15 degrees Celsius? So I use the q = mcΔT formula 2100J = (312 g)c(85 °C - 15 °C) I'm not sure if I did it right.

Oh, okay. You multiply the numbers. I was dividing it for some reason. Thank you, you are a lifesaver.

i don't get it? heat lost? ahhhh. this is very fustrating.

To be honest, I thought you suppose to subtract everything from 100. I'm being dumb. I don't know where I get 85 from. Forget that. So, how do I solve this problem?
