Question

2 the specific heat of wood is 2.03 j/g·°c. how much heat is needed to convert 550 g of wood at 0°c to 10°c?

Explanation:

Step1: Identify the formula

The formula for heat $Q = mc\Delta T$, where $m$ is mass, $c$ is specific - heat capacity, and $\Delta T$ is the change in temperature.

Step2: Determine the values of variables

$m = 550\ g$, $c=2.03\ J/g\cdot^{\circ}C$, $\Delta T=T_{2}-T_{1}=10 - 0=10^{\circ}C$.

Step3: Substitute values into the formula

$Q=550\times2.03\times10$.
$Q = 550\times20.3$.
$Q = 11165\ J$.

Answer:

$11165\ J$
