Question

Glass has a specific heat of 0.16 calories/gram°C.

Answer 1

Calories heat added = Mass of glass times temp. increase times specific heat of glass

calories (small calories) = l.0 g x 20 degrees x .16 calories/gm/degree C = 3.2 calories

Answer 2

Answer:

3.2 calories

Explanation:

The state of aggregation of the glass does not change, as its temperature increases, it is a sensible heat, because it depends on its temperature.

The sensible heat formula is

$Q= m.sh.T$

$sh= 0.16\frac{cal}{g C}$

$m= 1.0 g\\T= 20C$

$Q= 1.0 g.0.16\frac{cal}{gC} .20C\\ Q= 3.2 cal$

1.0 gram of glass will rise 20.0°C when 3.2 calories of heat are applied
