Calculate the heat (in J) required to raise the temperature of 3.02 g of solid silver from 22.3 degrees Celsius so solid silver at 47.0 degrees Celsius?

17.9 joules

Explanation:

The quantity of Heat Energy (Q) required to heat solid silver depends on its Mass (M), specific heat capacity (C) and change in temperature (Φ)

Thus, Q = MCΦ

Given that,

Q = ?

Mass= 3.02g

C = 0.24J/g°C

Φ = (Final temperature - Initial temperature)

= 47°C - 22.3°C = 24.7°C

Then, Q = MCΦ

Q = 3.02g x 0.240J/g°C x 24.7°C

Q = 17.9 Joules

Thus, 17.9 joules of heat isrequired.

the answer for sodium is 0.186

the answer for rubidium is 0.251
