Question

The specific heat capacity of silver is 0.06 cal/g°C. How much energy is needed to flow into a 5-gram sample to change its temperature from 10°C to 11°C?

Answer 1

The answer is 0.3 cal.

Answer 2

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.
