If 136 J is required to change the temperature of 8.75 g of nickel by 35.0 K, what is the specific heat capacity of mercury?
a.0.0294 J/g·K
b.2.25 J/g·K
c.0.444 J/g·K
d.0.311 J/g·K
e.0.417 J/g·K

Brain Dying, math killing me.
Oh yeah the answer is 0.444 :D

Your question is confused because it includes both nickel and mercury. If it's really one or the other, the just use the equation:
q = mc(deltaT)
You are given q (136 J), m (8.75 g) and delta T (35.0 K). Just plug those in and solve for c.

RE: Calculating Specific heat capacity? I know the equation and everything(q*m*change in temperature*C) But im kinda confused on one problem of my worksheet. This time they give me in the problem (2000 J=Q, 10 C=change in temp, m=1kg) THere asking me to find the specific heat and i cant really figure it out
