How many joules of energy are needed to warm 5.00 g of silver from 25.0°C to 27.5°C? (The specific heat of silver is 0.24 J/g°C.)

3J

Explanation:

The following were obtained from the question:

M = 5g

T1 = 25.0°C

T2 = 27.5°C

C = 0.24 J/g°C

Q=?

Using the following equation Q = MCΔT to solve for the energy need, we have:

Q = MCΔT

Q = 5 x 0.24 x (27.5 — 25)

Q = 5 x 0.24 x 2.5

Q = 3J

supongo que te refieres al paralaje estelar (observable).

si es así, entonces se puede inferir que la estrella está a más de 200 parsecs.

we can conclude that the melting point of table salt is above room temperature (it's actually 801 deg c). the melting point of mercury must be below room temperature (- 39 deg c).
