Answer 2

Answer:

91.728 cal required to increase the temperature 11 °C to 23 °C.

Explanation:

Mass of the alcohol ,m= 13 g

The specific heat of the alcohol,c = 0.588 cal/g °C

Change in temperature = $\Delta T=23^oC-11^oc=12^oC$

Heat required to increase the temperature be Q.

$Q=mc\times \Delta T$

$Q=13 g\times 0.588 cal/g ^oC\times 12^oC=91.728 cal$

91.728 cal required to increase the temperature 11 °C to 23 °C.
