Answer : Energy needed, Q = 0.3 cal

Explanation :

Given that,

The specific heat capacity of silver, c = 0.06 cal/g °C

Mass of the sample, m = 5 grams

It changes its temperature from 10°C to 11°C,
$\Delta T=1^oC$

Energy need to flow is given by :

$Q=mc\Delta T$

$Q=5\ g* 0.06\ cal/g\ ^oC* 1^oC$

$Q=0.3\ cal$

So, the energy needed to flow into this sample is 0.3 cal

Hence, this is the required solution.
