Answer:
Nickel
Explanation:
To find what metal it is, first find the density
Density formula: mass ÷ volume
so.. 26.7 ÷ 3 = 8.9 g/cm^3
Nickel has a density of 8.9 g/cm^3 so nickel is the metal that is present in the ring
Heat required = Q = 40 kcal
<h3>Further explanation</h3>
Given
mass of 500 g ice
Required
Heat required
Solution
The heat to change the phase can be formulated :
- Q = m.Lf (melting/freezing)
- Q = m.Lv (vaporization/condensation)
Lf=latent heat of fusion
Lv=latent heat of vaporization
Lf for water = 334 kj/kg=6.01 kJ/mol = 80 cal/g
Phase change(ice to water)
Q= 500 g x 80 cal/g
Q = 40 kcal
