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?

0.012 cal
0.3 cal
0.56 cal
4.94 cal

Answer 1

0.3 cal

Step-by-step explanation:

Answer 2

Heat required to change the temperature is given by

`Q = ms\Delta T`

here we know that

`m = 5 gram`

`s = 0.06 Cal/g C`

temperature is changing from T = 10 Deg C to T = 11 Deg C

so here we will have

`\Delta T = 11 - 10 = 1 degree C`

now we have

`Q = 5 ( 0.06) (1)`

`Q = 0.3 Cal`
