A sample of solid tin is heated with an electrical coil. If 38.6 Joules of energy are added to a 14.4 gram sample and the final temperature is 36.0°C, what is the initial temperature of the tin?

Answer :

To determine the initial temperature of the tin, we can use the equation:

Q = mcΔT

Where:

Q is the heat energy absorbed by the tin

m is the mass of the tin

c is the specific heat capacity of tin

ΔT is the change in temperature

First, we need to calculate the heat energy absorbed by the tin using the given values:

Q = 38.6 J

m = 14.4 g

Next, we need to determine the specific heat capacity of tin. The specific heat capacity of tin is typically around 0.23 J/g°C.

Now, we can rearrange the equation to solve for the initial temperature:

Q = mcΔT

ΔT = Q / (mc)

Substituting the values into the equation, we have:

ΔT = 38.6 J / (14.4 g * 0.23 J/g°C)

After calculating the value of ΔT, we can subtract it from the final temperature (36.0°C) to find the initial temperature of the tin.
