Chapter 2, Problem 2B.2ST

Interpretation Introduction

Interpretation:

The value of q when the sample of liquid raise the temperature by ${5.23}^{0}C$ and supplied with $124J$ of energy has to be calculated.

Concept Introduction:

For a specified system, the heat capacity $C$ of any substance is given by

$C=\frac{q}{\Delta T}$

Where, $q$ is the heat transferred and $\Delta T=T{f}_{}-T_i$ is the temperature change in the system.

The energy supplied as heat from power is given by $q=P\Delta t$, where $P$ is the power in watts $\left(1W=1J{s}^{-1}\right)$.

Where change in temperature, $\Delta T=\frac{q}{C_p}=\frac{q}{n{C}_p}$, $n$ is the number of moles and $C_p$ is the constant pressure heat capacity of water.
