Question

1) In this virtual lab, you will use coffee cup calorimetry to determine the specific heat, c, of a metal.Imagine that, in lab, you record the mass of a piece of metal, mmetal, asm(metal) =45.00 gIn the next step of the lab (as shown in the animation to the left) you heat up the piece of metal. Play the animation, and record the metal's highest temperature, Tmetal.Tmetal= _____c*(it start at 22c and heat up to 83c)2)In another step of this lab, you record the mass of water (mwater) in a coffee cup asm(water)= 130.00 gWhat is the initial temperature of the water, Twater1, in the coffee cup as shown to the left?Twater 1= ____c*In the next step of the lab (as shown in the animation to the left) you place the hot piece of metal into the cool water. Play the animation and record the final temperature of the water, Twater2.Twater 2= ____c*(it start at 22c and heat up to 25c)With the information above and the specific heat of water, 4.184 J/(g·°C), you calculate the specific heat, c, of the metal.

-(mcTf)metal= -(mcTf)water-(45.00g x c x 61) = -(130.00g x 4.184J/(gC) x 3)-2745 = -1631.76(-1631.76) / (-2745) = .5944J/(gC)

Katie is right... she just needed to be more explanatory..45.00 x c x (83 Temperature metal final- 22 T metal initial)= 130x 4.184 j/(gC)x (25 T water final -22 T water initial)45 x c x 61 = 130 x 4.184 x 32745c = 1631.76etc...
