Answer:

7g/cm³

Explanation:

Given parameters:

Mass of the mineral  = 21g

Volume  = 3cm³

Unknown:

Density of the mineral  = ?

Solution:

Density of a substance is the mass per unit volume of the substance.

 Density  = \frac{mass}{volume}  

  Now insert the given parameters and solve;

  Density  = \frac{21}{3}   = 7g/cm³

The mineral with a density of 7g/cm³ is Galena, an ore of lead.

One hundred fifty joules of heat are removed from a heat reservoir at a temperature of 150 K. What is the entropy change of the
Sidana [21]

Answer:

ΔS surrounding (entropy change of the reservoir) = -1 J/K

Explanation:

Given:

Change in heat (ΔH) = 150 joules

Temperature (T) = 150 K

Find:

ΔS surrounding (entropy change of the reservoir)

Computation:

ΔS surrounding (entropy change of the reservoir) = - ΔH / T

ΔS surrounding (entropy change of the reservoir) = - 150 / 150

ΔS surrounding (entropy change of the reservoir) = -1 J/K
