Explanation / Answer

Since it is a video demonstration and the data is not given i am giving the steps to solve

Step 1: Play the first video and check the peak temperature of the metal, let this temperature be Tmetal(high) which will be the answer to first blank

Step 2: Assuming the second image, shows the water temperature before addition of metal therefore Twater1= 23C

Now after adding the metal record the temperature, that will be Twater2

Now you would have Twater1,Twater2 and Tmetal(high)

Now for calculating the specific heat capacity

Step 3: Heat lost by metal = Heat gained by water

Let the specific heat capacity of metal be c

mass of metal * specific heat capacity of metal * change in temperature = mass of water * specific heat capacity of water * change in temperature

45g * c * (Tmetal - Twater2) = 130g * 4.184 * (Twater2-Twater1)

Now you know all Tmetal(high), Twater 2 and Twater1,just substiute the values or provide me the data to get the value of c
