 +===== - Introduction =====
 +The goal of the experiment is to measure the specific heat capacity of kerosene and compare it with the given value for finding the accuracy of the measurement.
 +
 +Same amount of heat $Q$ is given to 100 ml of water and kerosene, so
 +
 +$$ Q = m_w c_w \Delta T_w = m_k c_k \Delta T_k $$
 +
 +where $m_w$ and $m_k$ are the mass of water and kerosene, $c_w$ and $c_k$ are the **specific heat capacity** of water and kerosene, and $\Delta T_w$ and $\Delta T_k$ are the rise in temperature due to the given heat for water and kerosene. Therefore
 +
 +$$ c_k = \frac{m_w c_w \Delta T_w}{m_k \Delta T_k} $$
 +
 +which can be used to measure $c_k$. Define specific heat capacity using the unit J g$^{-1}$ K$^{-1}$.
 +
 +Calculate the mass of water and kerosene given the volume $V$ and density $\rho$ using the relation
 +
 +$$ \rho = \frac{m}{V} \Rightarrow m = V \rho. $$
 +
 +The volume is 100 ml where 1 ml = 1 cm$^3$. The densities of water ($\rho_w$) and kerosene (\rho_k) are given below.
 +
 +^ Material ^ Density [g cm$^{-3}$] ^ Specific heat capacity [J g$^{-1}$ K$^{-1}$] ^
 +| Water | $1.00$ | $4.19$ |
 +| Kerosene | $0.82$ | $2.40$ |
