Need help with my lab report for specific heat of unknown metal
Need help with my lab report for specific heat of unknown metal! I need to Find the Specific Heat of Al! I know its Q= M x Cs x Change in Temp I am getting a such a high number am just confused if its right. Here is what I got in Lab: Aluminum Mass of Metal (Mm): 6.128g Mass of water (Mw) : 25 mL Temp of water in calorimeter: 23.6 C Temp of metal in water-bath: 100 C...

Heat, q, is energy transferred between a system and its surroundings. For a process that involves a temperature change q=m⋅Cs⋅ΔT where Cs is specific heat and m is mass. Heat can also be transferred at a constant temperature when there is a change in state. For a process that involves a phase change q=n⋅ΔH where, n is the number of moles and ΔH is the enthalpy of fusion, vaporization, or sublimation. The following table provides the specific heat and enthalpy...

A 32.5g cube of aluminum initially at 45.8 C is submerged into 105.3g water at 15.4 C
A 32.5g cube of aluminum initially at 45.8 C is submerged into 105.3g water at 15.4 C. What is the final temp of both substances at thermal equilibrium. Assume the al and the H2O are thermally isolated from everything else)Specific heat cap Al= .903Specific heat cap H2O= 4.18I understand this problem but In my math i get to:(DeltaT) Al = -14.998 X (DeltaT) H2OAnd im lost. Anyone able to explain the completion of the problem? Any help is greatly appreciated

Calculating specific heat capacity A constant-pressure calorimeter is often used to find the specific heat capacity of a substance if it is not known. A known mass of the substance can be heated and added to water of known mass and initial temperature. Since the specific heat capacity of water is known ( C s,water =4.184J/(g⋅ ∘ C)) , the amount of heat transferred to the water can be calculated by measuring the final temperature of the mixture at thermal...

We did the lab of latent heat of fusion of ice, and I am
confused that what the 'water equivalent' represents.
I thought it is the amount (kg) of water, but it is
mccc according to this lab manual, which unit
is (J/oC).
Please answer what the water equivalent represents and the unit
of it.
